All Planets Are Earth-Like	comment	That science fiction trope where planets fall into two categories: Earth-like (solid, with a human-breathable atmosphere and the same gravity, even if completely barren), and gas giants. And often, many of the gas giants have Earth-like moons. Even the most inhospitable of Single Biome Planets are not immune. There is, of course, a certain subjectivity regarding the definition of "Earth-like". In some works, "Earth-like" means that a human being can walk around without a pressure suit and not die, but everything else (the presence of animals and plants, the weather, the gravity, and so on) might be vastly different. In other works, "Earth-like" means not only are pressure suits unnecessary, but a person can eat the plants and animals, drink the water, walk around in the gravity without a lot of effort, survive the weather, and so on. Often justified by mentioning terraforming; series without terraforming invariably have many life-bearing planets that are perhaps more similar to Earth than most would consider plausible.note We don't actually know how common or uncommon Earth-like planets are in Real Life, and thus it's hard to judge "realism" here objectively. For what it's worth, NASA's Kepler mission so far suggests maybe one in about 30,000 stars might have a planet that's Earth-like in terms of size and orbit, at least, though not necessarily in terms of atmosphere or other important details. There are estimated to be between 200 and 400 billion stars in the Milky Way, so that's at least six million inhabitable planets in those terms, before counting near-Earth-sized moons... needless to say, even if that numberâ€™s only a small percentage of the many exoplanets out there, in human terms itâ€™s quite a promising number. Hell, even with terraforming, there still would not be too many planets in one solar system that might be human-inhabitable without some sort of huge sunlight-focusing and gathering apparatus in orbit, since the planets' distance to the sun seems to be the main factor. There are also some theories that an Earth-like planet would be the ideal type for (carbon-based) life (but again, this is just a theory). Additionally, even if a planet is terraformed, it still would look mostly the same as it did before, except a different color (if Mars were terraformed, it would still have its volcanoes and craters). Can also be justified by The Law of Conservation of Detail. Most people are unlikely to visit a planet where they can't breathe, so Earth-like planets will tend to be the only places anything interesting is happening. This frequently happens because at least half of science fiction shows are shot in British Columbia, which conveniently happens to be located on an Earth-like planet (Earth). In live-action TV, this is inevitable, since creating a convincing alien planetary setting tends to require (a) a great deal of budget and F/X spent on a set that must be built very quickly and most likely will not be used again, and (b) any actors appearing in that setting to don costumes (also expensive, but more potentially reusable) which, if they are convincing full-protection envirosuits, will usually obscure the face and make acting more difficult. (See Rubber-Forehead Aliens for a reverse example of that problem.) Movies, animation and novels, less bound by time and budget concerns, have a somewhat better record, but even there the ability for human characters to see, be seen, and interact with each other without significant inconvenience tends to trump realistic assessment of xenoplanetary environmental conditions. Of course, this makes it problematic if some species wants the resources of a certain planet and are not concerned about the fate of its inhabitants. You'd think that a universe full of uninhabited planets would be a wonderful resource for metals and other minerals, but no. There's an actual astronomy term for Earth-like planets: Earth analogsnote And remember here that all we can say with our current technology is that a given star has one or more planets similar to ours in terms of mass and/or diameter, and that are located at a distance of their star where conditions in theory allow liquid water to exist. So far, the actual conditions on them besides at best some rudimentary data on their atmospheres are unknown and are pure guesswork at worst. Said planets may be Venus analogs instead. See also Single-Biome Planet. Contrast Death World. For depictions of planets in our own Solar System as more Earth-like than they are, see Once-Green Mars, Solar System Neighbors, Strolling on Jupiter and Venus Is Wet. Since this trope is so ubiquitous, only Lampshade Hangings, subversions and aversions ought to be listed.

All Planets Are Earth-Like / int_12fd8e7f	comment	In Destiny: Most of the planets you can visit in the solar system are relatively Earth-like (in that humans can walk around on them and breathe the atmosphere) but this was due to the Traveler going around and terraforming them.Venus, Mars, Io, and Titan, for example, are all inhabitable by humans, while Earth's Moon has at least some atmosphere. That said, each planet retains features from before its conversion. For example, Venus◊ is still a yellow planet with a thick atmosphere and strange weather patterns, but now it can support vast jungles and human cities. Mars◊ remains a red, sandy desert, but it's atmosphere is warm enough, thick enough, and breathable enough for humans. Io◊, despite being a tiny moon, was turned into a verdant green Earth-like world. Mercury◊ was intended to be a very Earth-like world by the Traveler, but the Vex came along and converted the entire planet into a vast Vex machine. And while 7066 Nessus◊ looks Earth-like, only with red vegetation instead of green, the entire planet is another Vex machine world and it has an atmosphere intensely toxic to humans.

All Planets Are Earth-Like / int_169f043b	comment	For most part, StarCraft averts this, as the vast majority of planets in the Koprulu Sector are said to be largely inhospitable to human life. In the original game, only Aiur appears to be anything close to an Earth-like planet, with most other planets supporting permanent human habitation depicted as semi-arid wastelands. According to the backstory presented in the manual, the colony ships were originally sent to colonize a habitable planet that was one year away from Earth, but ended up traveling blindly through space for twenty eight years when their navigation systems shut down. The supercomputer controlling the ships forced them to land on the nearest habitable planets before life support systems failed. Expanded universe materials and the sequel game expand the number of Earth-like planets, with Umoja, Agria, and Meinhoff being notable examples. Korhal IV also used to be a nice place to live, but most of the planet was flattened by nuclear missiles before the start of the first game.

All Planets Are Earth-Like / int_17bfcf60	comment	In the Homeworld series, while Hiigara falls under this trope, Kharak is only partly habitable, being a harsh desert planet that only the poles are comfortably habitable, while maintaining .98g gravity and breathable atmosphere. Justified in the fact that since the original Hiigarans were exiled there, the planet must've been chosen specifically as being harsh, but not too inhospitable. Except the prequel Homeworld: Deserts of Kharak reveals that Kharak is getting less habitable every year, with the great desert pushing back on the habitable areas at the poles. This is why the Northern Coalition is investing heavily in space travel. It's either space or extinction for them. The Gaalsiens don't agree, though, citing an ancient prophecy about the god Sajuuk raining death from above for transgressions (they're actually right, in a way).

All Planets Are Earth-Like / int_18469d93	comment	Played straight in the Russian children's story "Journey to the Morning Star". Given that the story was written in 1960 and meant for kids, this is expected. The Lado system in the Coma Berenices constellation has three planets, all of which are (or were) Earth-like. The first planet, Aeo Tau (the titular "Morning Star"), is a virgin world full of prehistoric creatures such as dinosaurs. The second planet, Sino Tau ("Thunder Star") is a lush paradise with an advanced race of Human Aliens who are constantly at war with one another. The third planet, Etheri Tau ("Cold Star") is the oldest of the three and is no longer capable of supporting life, although it was once much like Aeo Tau. The Etherians are Human Aliens who have lived underground for thousands of years but must now relocate to Aeo Tau to survive. The warlike Sinots invoke The Right of a Superior Species and threaten any Etherian who sets foot on Aeo Tau with death.

All Planets Are Earth-Like / int_1e015a5d	comment	The Empire Strikes Back: It's not most definitely not a normal planet, but while the belly of the gigantic space slug lacks a breathable atmosphere, it apparently has normal gravity and pressure. Odd, as it's inside an asteroid in deep space. Han, Chewie, and Leia can walk around with only oxygen masks. Maybe the Millennium Falcon was able to extend its artificial gravity field or the asteroid field as a whole had some kind of atmosphere. Bespin apparently has a breathable oxygen-nitrogen atmosphere despite being a gas giant. This is probably actually more realistic than the space slug incident; it's theoretically possible that a thin layer of breathable atmosphere could exist in the upper atmosphere of a gas planet and if it's Saturn-sized or smaller then the effective gravity in its upper atmosphere could be Earth-like. That'd be an incredibly convenient coincidence, but, well, the galaxy is a big place.

Life-bearing worlds are so rare that the galactic races have agreed that no race must be allowed to destroy their world through pollution or war. Thus, if a race nears this stage, it must be "cleansed" from the planet, allowing this world to try again. Hence Klaatu's appalled reaction when the US Secretary of Defense calls Earth "our world," since the galactic races consider even the concept of a race owning their planet to be blasphemous.

All Planets Are Earth-Like / int_247422c7	comment	Honor Harrington: Played more or less straight, but there are subversions and at least one deconstruction. The Manticore system is extremely unusual for having three Earthlike planets (partly a result of the very large habitable zone created by its Binary Suns), and part of the Star Kingdom's backstory is that Manticore was so Earthlike that a native disease crossed the species barrier and killed the majority of the first wave of colonists. The creation of a constitutional monarchy and noble class was a solution for the survivors wanting to maintain political power over the replacements the colony recruited from offworld. Meanwhile Grayson looked Earthlike from a distance but turned out to have horrifically high concentrations of heavy metals. And San Martin's gravity is so high that people can't live at sea level because the atmosphere becomes dense enough to kill an unprotected human. Done to extremes with the very Texas-like planet of Montana that just happens to have a lot of animals that are almost exactly like real Texas animals. And everyone is a stereotypical ornery cowboy. It was handwaved by describing it as a planet colonized by very Texan-like people determined to preserve stereotypical ornery cowboy lifestyle.

All Planets Are Earth-Like / int_28340943	comment	Averted in The Interdependency series. In the 1500 years humanity has explored the galaxy (although, to be fair, the number of systems is actually only 47 due to Hyperspace Lanes), only one Earth-like planet has been found. Every other world is either a barren rock or a gas giant. Oh, and the link to Earth itself was lost over a millennium ago. Thus, most of humanity lives aboard space stations or in domed cities, with only a few million living on End, the habitable world. In fact, most people are so used to living in controlled environments that they view End as a shithole, partly because it's so far away from Hub, the center of the Interdependency. With the looming collapse of the Hyperspace Lanes, End is liable to be the only human colony to survive because it doesn't need machines to support the population. Later on, though, it's revealed that habitable worlds are more common in other parts of the galaxy settled by humans, particularly in the Earth Empire and the Assembly.

All Planets Are Earth-Like / int_2ae406c1	comment	Averted in Sid Meier's Alpha Centauri — Planet is called "earthlike" at the very beginning, yet some of the many problems you face in the course of colonizing Planet are the poisonous atmosphere (90% nitrogen rather than 78%, combining with higher gravity and a thicker atmosphere to give you nitrogen narcosis if you try to breathe it), inedible plantlife, and hostile (very, very hostile) native fauna. And the game doesn't hide the fact that even such "earthlike" planets are very rare. The planet in the Creator-Driven Successor Civilization: Beyond Earth is also poisonous to humans. Instead of xenofungus, colonists have to deal with poison gases that can easily kill unprotected humans. There are three main approaches to dealing with the planet: Harmony (biologically modifying humans to survive there), Supremacy (turn humans into cyborgs who aren't as susceptible to the hostile environment), and Purity (aggressive Terraforming in order to make the new planet into a second Earth). The Rising Tide DLC adds hybrid approaches/affinities, explaining them as compromises.

All Planets Are Earth-Like / int_3c9a6ac7	comment	Averted in Odysseus Kosmos and His Robot Quest. There are only two planets of note in the Gargan-Hope binary system: Calcutta and Ithaca. Ithaca is an ice-covered lifeless rock, with the "ice" actually being composed of inert gases, not water. The surface temperature is only about 30 degrees above absolute zero. Calcutta is a super-Earth about 1.5 times the size of our planet. The average surface temperature is zero Celsius, and yet there's liquid water on the surface, which is probably the only reason the crew went down to investigate. Since Calcutta is close to Gargan, it experiences a lot of Time Dilation, to the point where minutes on the surface translate into years aboard the ship.

After Varx offers to whisk Paul to another planet for adventure, Paul (who thinks he's dreaming) jokingly worries that he might be dropped on the Moon or some other inhospitable place. Varx assures him that they have an oxygen planet all picked out. Later, when the four go on the Vasyn quest, the three planets they visit are very Earthlike (one of them being an actual parallel Earth) but again, these were all picked out for them.

All Planets Are Earth-Like / int_5a0d652b	comment	Warcraft only has three explicitly known planets, Azeroth, Draenor, and Argus, all of which are or were very earth-like. Draenor was ripped apart by magical experiments and drained of its life by demonic influence, which makes it a very alien place... with the exception of Nagrand, which somehow remained untouched. What else is left of the planet still qualifies as earth-like as far as this trope is concerned. Life is still possible (even though half of the zones have no water or any plantlife other than herbs, but that's more an issue of Gameplay and Story Segregation). However, the alternate Draenor players visit in Warlords of Draenor is set in the past before all the aforementioned planetary corruption happened and looks perfectly normal for the most part. Argus was turned into a smoldering Death World by the Burning Legion before being made into their central base planet, but flashbacks in Legion show that it used to be just as earth-like as Azeroth and Draenor.

Most of the planets in the series are fairly Earth-like, though there are some exceptions where the team has to wear special space suits to explore them. This is explained as the Goa'uld (and before them, the Ancients) having terraformed the planets millennia in the past. And once again, Stargates are placed by once-humanlike Precursors who would have no reason to put one on a world that would kill you the second you exited. Some of them were once Earth-like, but have since suffered some sort of disaster that has rendered it uninhabitable. And then, there are those examples where Planets are absurdly present-day Earth-like to the point where Ikea furniture would fit right in. Particularly common in later seasons and Stargate Atlantis. Lampshaded in "Prodigy", when Carter's arrogant young cadet emerges from the Stargate and says, "So this is another planet? ... Doesn't look that different from home." They actually played with/subverted this trope in the teaser for a Season 9 episode. Most of the alien worlds, as stated, look almost exactly like the woods around Vancouver so the audience wouldn't be too surprised to have an episode open with a Jaffa running through one of these alien forests... until he gets hit by a truck and you find out that he was on Earth All Along. O'Neill takes a swipe at this (and at California Doubling) at one point. "Why do they always look like Canada?" In "Heroes, Part 1", SG-13 is doing a standard recon mission, and the team leader Col. Dixon takes bets on what they're going to find on the planet. One of his mauve shirts pipes up with "trees". Dixon says he's "disqualified for being a smart-ass." Double Subverted in Season 1's "Solitude" when Sam and Jack are trapped in an ice cave. Sam gets a look at the surface outside and declares it's an ice planet and there's no way out. In actual fact, they're on Earth, in Antarctica, which was a temperate zone when the Beta Gate was built there millions of years ago. Stargate Universe averts this and Human Aliens by having most worlds visited barren and lifeless and mostly only good for picking up the one or two useful natural resources before moving on. And SGU is a good example of why this trope falls under Acceptable Breaks from Reality: barren rocks really aren't that interesting of a setting. However, sometimes the ship stops at a planet automatically, and the team will explore others that happen to be in range. The ship rarely stops at nasty ones, but with these others, you're rolling the dice. And as always, the then-humanlike builders of the gates and the ship have no reason to put gates on useless or deadly worlds.

Nonetheless, most have at least a few areas where very hardy humans can survive, albeit with high mortality rates (the poles of Fyrstaat and Tanith, the equator of Haven). A rare few, like Sparta, are nearly ideal for Earthlife, if slightly off in gravity and length of day. And some worlds, like New Caledonia, require extensive terraforming. The alien-inhabited Mote Prime requires respirators. The double-planet system of Franklin/New Washington required Earth plants to be genetically altered for the red sunlight. "Haven", the setting of War World, is a case of Pournelle getting together with Niven and asking, "Exactly how horrible can we make a planet while still letting humans breathe the air?"

So while Earth-like planets do exist, they are very rare, meaning that some colonization fleets have had to resort to terraforming less hospitable worlds instead. To make things more complicated, many of the most desirable Earth-like planets are already inhabited by native intelligent life.

Despite this, no race has more than a few hundred colonies. This is because habitable planets are few and far between. The Haptors have been in space for over three millennia and have about two hundred worlds. But their territory also includes thousands of systems they don't bother settling because they have no habitable planets. Humans have gotten good at terraforming barely habitable planets (after practicing on Mars), but it seems that only the Solar System has space habitats and domed cities on airless planets and moons (and only because many of those were built before humans got interstellar travel).

All Planets Are Earth-Like / int_7988cb68	comment	Mass Effect notably averts this; the vast majority of the planets encountered are actually very hostile to human (or most) lifeforms. This makes those inhabitable worlds that can be found all the more valuable. "Vast majority" here meaning that only three planets shown in the first game are safe for humans, in a game that shows around a hundred. Most of the planets you visit require spacesuits and sealed environments for survival, and sometimes not even your Powered Armor/space suit will keep you alive for very long. The 80%+ of planets you don't visit are often even more inhospitable. It's also noted on the info screens for several planets note that what makes them unsuitable for humans make them perfect for volus/hanar/elcor etc. A few planets actually are more like subversions, too. Like Nodacrux, the planet with a much higher oxygen concentration than Earth's. It's enough for humans to feel plenty comfortable, like being in a hyperbaric chamber... but it makes thunderstorms absolutely devastating to anything they catch in their path, and vegetation goes up like tinder in amounts that make the California wildfires look like campfires. Not to mention huge insects and plants that give off pollen that causes death by allergy in seconds. Even planets that humans actively colonize aren't all Earthlike. Eden Prime, which you visit at the beginning of the game, is pretty close to Earth, except for its sixty-four hour days.

The reason there aren't nearly as many inhospitable worlds visited past the first game is because the open-world exploration was mostly removed. Mass Effect: Andromeda is basically about the main character trying to find an actual Earth-like planet for galactic colonization, after all the scanned "Golden Worlds", supposedly Earth-like planets, turned out to be Death Worlds. Later on in the game, the earthlike-ness turns out to have been because a group of sufficiently advanced aliens went to a lot of trouble to make them nice and cozy for their own ends.

The atmosphere has plenty of oxygen, it's just that we can't breathe the atmosphere because the composition of the other elements in the atmosphere more resembles the Earth during the Permian extinction — a whopping 18% carbon dioxide; trying to breathe that is like trying to breathe with a plastic bag over your head, and 0.1% hydrogen sulfide, which is extremely toxic to humans at even half that amount, being capable of damaging the mucous linings in the lungs. The Na'vi, along with every other land animal, are able to breathe in this environment despite it being hostile to the vast majority of earth-like life because the Pandoran life actually evolved there. Additionally, just about every plant or animal is inedible/toxic to humans. The low gravity is also why everything is so much bigger on Pandora; it can afford to be, on account of the lower gravity.

However, you can research technologies to colonise all of them. Except possibly on the highest "usable worlds" setting, nearly all of the worlds you encounter are not only not earthlike but completely uninhabitable quality 0 gas giants or tiny balls of scorched or frozen rock. Although there are weird mega-events that occasionally roll through and turn an entire system into medium to high quality potential colonies, regardless of the size or nature of the planets.

All Planets Are Earth-Like / int_90e2f673	comment	In BattleTech, 'Earthlike' is variable. No planet is exactly like Earth in terms of comfort for humans, which is commented on by those who are lucky enough actually travel there. Most of the settled worlds are fairly close, though there are wild exceptions, like the domed cities of Sirius V (the atmosphere is poisonous), or Tharkad, the Lyran capital, which is in a serious Ice Age (though contrary to persistent fan rumor, it is not completely frozen and does have an equatorial tropical band, something the writers take pains in pointing out on multiple occasions). Justified in that Humans would naturally pick the Earth-like planets to settle first. The Star League in its heyday did in fact do rather a lot of terraforming and other mega-engineering projects. Then the Succession Wars started and military budgets took priority over such expensive flights of fancy and massive terraforming projects stopped.

All Planets Are Earth-Like / int_9a0c0ffa	comment	While it seems to be the case in The History of the Galaxy with several hundred human colonies in known space, that number is only a tiny fraction of the total number of colony ships sent out during the Exodus. According to the author's website, that number is 7023. This means that the vast majority of those ships never found a habitable planet to settle. In fact, humanity's very first extrasolar colony ship Alpha ended up in a system with a barely habitable planet and had to implant colonists with metabolism adjusters that drastically reduced their lifespans, just so they could survive on the surface. One planet is known for being entirely covered in ice. The colonists there had to build marvelous subglacial cities that are now largely empty once contact with other, nicer colonies was reestablished. One novel mentions that anyone, who finds an unsettled habitable world, can expect to retire incredibly wealthy on the finder's fee alone. In recent years, corporations are starting to settle new worlds with machines in order to build up colonies and prepare planets for settlers (i.e. terraform them).

The planet Elba II had a poisonous atmosphere that would kill humans breathing it before very long, "The Way to Eden" had a planet that was technically habitable (right sunlight and air quality), but all the flora excreted a deadly acid, and the fruit was lethal. The TOS Writer's Guide acknowledged this trope right from the start: the formal orders to the captain of the Enterprise found therein contained instructions that the ship would mostly confine its operations to Class-M planets, though the ship did, of course, carry spacesuits.

When unexpectedly asked about what Naboo is like, the Game Master automatically responds: "Um... Earth-like?", and the players notice that it's "convenient". Later, when they approach Tatooine, they ask the GM if it's "conveniently Earth-like again", and he hastily assures them that it's a planet-wide desert. Only, for the purposes of this trope, it's still Earth-like enough. "So it's Mad Max World?" Later subverted somewhat with Naboo, as well, as they figure out that, while it may have an Earth-like surface, its geology would have to be radically different from ours for some of the things they do in the game to be possible.

For all of them, extensive terraforming is required before sending in the colonists. Amethi was a frozen world with very little atmosphere when the first settlers came, and a scene depicts the startled reactions of a bunch of children who see a cloud for the first time. On Thallspring the soil bacteria and other biota make it necessary for the MegaCorp running the colonization efforts to clear out all life in large swaths of land via periodic orbital gamma laser "soaks", in preparation for colony expansion. The process is stated to kill all bacteria down to a few meters underground. Santa Chico has a very high oxygen content, and its biosphere is a biochemical and medical goldmine, which is why the colonists modified themselves to adapt and eventually began using Organic Technology, only to revert to an agrarian society of bizarre xenophobic Furries once they grew bored with the Mega Corps periodically plundering their planet.

And as always, the then-humanlike builders of the gates and the ship have no reason to put gates on useless or deadly worlds.

All Planets Are Earth-Like / int_c2f4431b	comment	Used with twists in The Citizen Series: uninhabitable planets are simply ignored by the characters due to the nature of Faster-Than-Light Travel involving transiting into and out of the Continuum directly onto planet surfaces (or into the atmosphere). Even then there's variety: Nengue is volcanic and only marginally habitable, settled only to support a trading post between the Cutter Stream and the Riders. Mudball is geologically inert and has nothing but single-celled life (fortunately, most of it is photosynthetic algae so the atmosphere is breatheable). Allenson also once endures miserable conditions besieged during a monsoon season on a perfectly Earthlike planet.

All Planets Are Earth-Like / int_c43df4d8	comment	Doctor Who: Nearly every alien planet ever featured on the show has Earth-normal gravity and atmosphere. The First Doctor serial "The Web Planet" has the distinction of being set fully in an alien galaxy, with (aside from the Doctor and his companions) a full insectoid supporting cast and environment. The Earthlings (and Gallifreyans) did not wear space suits, but at times did suffer from weakness owing to the difference in atmospheric composition. It was parodied in the First Doctor serial "The Daleks' Master Plan", when the Doctor was nervous about the effect of poisonous gases in the atmosphere of a city on his companions. It turned out to be an industrial city Oop North, and the gases were just then-normal levels of air pollution. In the Second Doctor serial "The Moonbase", the characters wore special atmosphere suits to explore the Earth's Moon. They were never seen again. The show's writers most likely did it because it was set somewhere that the viewing audience already knew didn't have a breathable atmosphere. Space suits showed up again much, much later, in the Tenth Doctor story "The Impossible Planet"/"The Satan Pit". He didn't make them on his own though, but borrowed them. In the Tenth Doctor episode "Midnight", the title planet is totally unlivable (except it turns out it isn't, but that's beside the point); it's apparently one big lump of crystal with no atmosphere and a star that emits very deadly rays. But Professor Hobbes goes on about this like it's remarkable for a star system NOT to support life. The Doctor's spacesuit makes a return in "The Waters of Mars", set guess where. The Eleventh Doctor is seen using the same suit again in "Hide", though equipped with a brand new helmet design this time around. He wears it on Earth, at the beginning and end of its existence. The Twelfth Doctor breaks out the spacesuits again in "Kill the Moon", for obvious reasons. In Series 10, the Twelfth Doctor and company go to Mars, so naturally they wear spacesuits — a new design this time.

The game takes place on a number of celestial bodies in the Solar System and around the nearby stars (one mission takes place on a very large comet), but of these, only 2 planets are actually suited for human habitation. One of the is a desert planet reminiscent of the one in Stargate (complete with ancient alien pyramids), while the other is a very Earthlike planet called Eden. The main characters are visibly surprised when they see a video from the surface, and some even suspect that it's actually old Earth footage. All of the above locations are made a bit less pleasant by the Morphidian presence.

All Planets Are Earth-Like / int_ce4f5b7d	comment	The Beta Caeli system in Alien Legacy has not one but two Earth-like planets, named after the Greek goddesses/Titanesses Rhea (mother of the gods) and Gaea (earth goddess). Gaea is the third planet like Earth but lacks a satellite. Despite this, it has plant and animal life, even though it would be difficult for them to evolve without tides. Rhea is the second planet like Venus but has the same conditions and even life forms as Gaea. The game implies the presence of a Moon-sized satellite prevented a Venus-like greenhouse effect. The rest of the planets are similar to Solar System planets. All planets (including satellites and asteroids) except for gas giants are colonizable. However, the late-game reveal that the two habitable planets were seeded by the H'riak may imply that this is not a natural occurance. The existence of the Centaurians also implies a habitable planet in the Alpha Centauri system, although whether it's habitable for humans is anyone's guess, as nothing is known about the Centaurians except that they're Absolute Xenophobes.

As depicted in the two series and the semi-canon poster map the Twelve Colonies themselves are all Earth-like to varying degrees; habitability ranges from pleasant worlds like Caprica and Leonis to more inhospitable ones like Aquaria (a planet-sized Antarctica) and Libran (overwhelmingly hot jungle). There are also references to moons and planets from the First Cylon War that apparently have snakes and other creepy-crawlies, so they are presumably Earth-like as well. Outside of the Twelve Colonies, however, the galaxy is a much more barren place. Throughout a journey covering thousands of light years, the Fleet encounters only five other Earth-like worlds of varying habitability: Kobol (original homeworld of the Twelve Tribes), New Caprica, the Algae Planet, Earth (home of the Thirteenth Tribe) and the second Earth, which is settled in the finale.

Justified, as each planet is where your creature will live and evolve. This trope is utterly averted in the Wide-Open Sandbox Space Stage, where most planets are T0 inhospitable rocks, and the few life-bearing planets are mediocre T1. A nice naturally-occurring T3 planet is fantastically rare. If you want a nice planet, you'll need to Terraform it.

There are Earthlike planets out there, as indicated by the Sh'daar numerical designation for humanity including our preferred atmosphere and the fact that the Agletsch don't seem to have a problem with it, but they are few and far between. Only two human-settled alien worlds allow the colonists to survive unprotected: Osiris and Vulcan (which happens to be located exactly where Star Trek's Vulcan is supposed to be), and of the two, only Vulcan has edible native life (Osiris has Mirror Chemistry). Unfortunately, one of the hostile races humanity later encounters has evolved on an Earth-like world (even though they look like large balls with dozens of mouths) and is capable of digesting terrestrial life forms... including humans.

And inhabitable planets themselves are divided into eleven types (Earth is "continental") and species favor the same type of planet they were native to, though populations can be genetically modified to favor different planet types and inhabitable planets can be terraformed into different types. Of particular note are Gaia Worlds, which are somehow 100% inhabitable to everyone and are considered "holy" by Spiritualists, though implied to be produced by Precursor terraforming projects (or the player when they unlock the late-game tech). And Tomb Worlds, which are nuclear wastelands inhospitable to everyone not native to such planets.
