** [[Literature/JohnCarterOfMars Green and Red Martians]], [[Literature/TheSpaceTrilogy Sorns]], [[Literature/GullivarOfMars Hither People]] and the ''ComicBook/MartianManhunter''. The ''Literature/WarOfTheWorlds'' Martians appear as extraplanetary invaders before giving up and turning to Earth.

** Mars has Green Martians from ''[[Literature/JohnCarterOfMars John Carter]]'' and Hrossa and Sorns from ''[[Literature/TheSpaceTrilogy Out Of Silent Planet]]''. Not forgetting the ''Literature/WarOfTheWorlds'' Martians that the series revolves around.

* ''Literature/EdisonsConquestOfMars'', an unauthorized sequel to ''Literature/WarOfTheWorlds'', has the Martians return in conflict not just with Earth, but also with giant beings from the dwarf planet (then considered an asteroid) Ceres. Their size comes from the very low gravity of Ceres.

** The Neptunians, four-armed purple aliens, come from the planet Neptune, as do the short elves that [[BadSanta Robot Santa Claus]] forces to work on the planet's north pole. The planet is depicted as a solid world instead of the gas giant it is in real life, and whether or not it was terraformed to be like that by the 30th century is never stated.

** The [[BlobMonster alien Blobs]] were heavily implied to come from Venus, before being confirmed as such in the licensed puzzle game ''Game of Drones''. In the series, it's suggested due to one of the blobs featuring in the ''Venus de Venus'' picture.

* No prizes for guessing what the ''westernanimation/BikerMiceFromMars'' find on Titan in the episode "Surfer Cats of Saturn", though they're a splinter group from the extrasolar Catalonians.

* ''ComicBook/AllStarComics'': In issue 13 each member of The Justice Society Of America is knocked out and sent to a different planet in the solar system. All of them encounter intelligent life on their respective planets, with Dr. Mid-Nite lampshading how improbable it is to find life on even one other planet. This occasion is actually when Wonder Woman first met and befriended Queen Desira of the winged women of Venus.
* ''ComicBook/MartianManhunter'': J'emm, Son of Saturn is part of a race descended from Martian colonists. Though referred to as Saturnians, they technically inhabit the planet's various moons.
* ''ComicBook/WonderWoman'' [[ComicBook/WonderWoman1942 Vol 1]]: Wonder Woman becomes fast friends with the winged Queen of Venus, gains a nemesis in Mars who rules the ethereal Martians, fights and then becomes allies with the Emperor of Saturn, rescues an abducted woman from Pluto, and alongside the Venusians overthrows the despotic misandrist Queen of Mercury. Earth is also invaded by a group from Neptune.

* Pre-Crisis ''ComicBook/{{Superman}}'' comics had all nine planets of the solar system inhabited by at least one race.

* ''ComicBook/SensationComicsFeaturingWonderWoman'': In "Venus Rising" Diana accompanies a scientific expedition to Venus, where she and the scientists are surprised to find giant dragon-like [[LivingGasbag living gasbags]] which seem intent on tearing apart their vessel.
* ''ComicBook/{{Shazam}}'': Captain Marvel villain Mister Mind came from Venus. While he looks like some sort of worm or caterpillar he's one of the more serious villains in Billy Batson's rogues gallery, being an alien conqueror. He was introduced before the Venera Program debunked Venus as a habitable world, but his home world remained the same and he got off-world by stowing away in a space probe.

* ''ComicStrip/DanDare'' features Venus and Venusians heavily, including reocurring villain Mekon.

* ''Literature/TheWeaponTooDreadfulToUse'' was a very early story by Creator/IsaacAsimov reprinted in Literature/TheEarlyAsimov about human oppressing native Venusians. [[spoiler: The Venusians have their own method of resisting, with the [[TitleDrop titular weapon too dreadful to use.]] ]]

* ''ComicBook/ActionComics:''
** During the course of his job as a [[SpacePolice Planeteer]] Tommy Tomorrow helps out some Jovians on Jupiter.
** Giovanni Zatara once thwarted a planned Saturnian invasion by tricking the shapeshifting Saturnians into thinking magical powers like his own were commonplace on earth.
* ''ComicBook/AllStarSquadron'': In the Post-Crisis continuity ComicBook/{{Starman}} (Ted Knight) was revealed to have traveled via Hyperspace to the Jupiter of another dimension, where the locals were MechanicalLifeforms like in his native universe of Earth-Two but much more friendly and fascinated by earth cultures.
* In ''ComicBook/CaptainMarvelAdventures'' the titular hero discovers that the natives of Saturn are being enslaved by extra-solar invaders and travels to the planet to expel the would be conquerors.
* ''ComicBook/DCOneMillion'' reveals that Neptune eventually developed aquatic life, and that aquatic life from other planets including Atlanteans of Earth have moved there due to the peaceful idyllic quality of life on the planet.
* UsefulNotes/TheGoldenAgeOfComicBooks [[ComicBook/JusticeSocietyOfAmerica JSA]] story "Vampires of the Void" features the inhabitants of Jupiter, metallic life forms who come to Earth and actually consume metal as food. They end up taking on the characteristics of the metal they eat, which is how the various JSA members are able to defeat them.
* In the early 1940s ComicBook/{{Hawkman}} came across a crashed ship from Neptune on earth. Everyone on board were giants who had perished in the crash and the egg he looted from the debris ended up in the hands of an evil scientist. Hawkman fought the boy who hatched from the egg to the youth's death.
* In Creator/MarvelComics continuity, Uranus was colonized by The Eternals millennia ago. Their interests have been represented on Earth by the original Marvel Boy, now called The Uranian (despite his actually being human.)
* In the very first ''ComicBook/TheMightyThor'' story, Dr. Donald Blake was visiting Norway when the arrival of the Stone Men of Saturn drives him to hide in a cave, where he finds a wooden stick which transforms into Thor's magic hammer, Mjölnir... and the rest is history. The Stone Men have since been retconned to be from outside our solar system and to have only had a ''base'' on one of Saturn's moons.
* In ''Wow Comics'' (a Golden Age Creator/FawcettComics publication later purchased by Creator/DCComics) Atom Blake had several adventures on the planet Mercury where the locals were small bug-like telepathic beings.

* ''ComicBook/AllStarSquadron'': ComicBook/TheSpectre was sent via hyperspace to the Pluto of another universe, where he discovered the two native groups (one evolved for the surface and one evolved to live under the ice) are locked in a generations long war.
* ''ComicBook/ChallengersOfTheUnknown'': The challengers once rounded up three giant plutonian animals wreaking havoc on earth and then handed them over to intelligent aliens from Pluto who safely removed the creatures.
* The ''ComicBook/{{Eternals}}'', of whom ComicBook/{{Thanos}} is a part, are native to Saturn's moon of Titan. They're descendants of proto-mankind created and modified by [[{{Precursors}} the Celestials]] who were eventually moved to Titan where they live to this day.
* ''ComicBook/LegionOfSuperHeroes'': Founding member Imra Ardeen, aka "Saturn Girl" is from Saturn's moon Titan, where the local people all have some degree of telepathy. Though more modern continuities tend to have them descended from Earth colonists rather than being aliens.

* ''Literature/TheSpaceOdysseySeries'': Europa turns out to have a complex ecosystem, including a number of intelligent species. The Monoliths convert Jupiter into a mini-sun in order to boost their development (and prevent their eventual extinction as Europa recedes from Jupiter and freezes solid), as their creators, [[SufficientlyAdvancedAliens the Firstborn]], believe their potential deserves to be explored. (Jupiter itself was also home to life, but all its organisms were simple creatures driven by instinct; the Firstborn decided it was worth sacrificing them for the Europans' sake.)

[[folder:WebComics]]
* In ''[[Webcomic/{{TheInexplicableAdventuresOfBob}} The Inexplicable Adventures of Bob,]]'' quite a few dwarf planets and other bodies in our solar system are inhabited, but it's implied they're mostly colonies and it's possible none of these aliens actually evolved here. Well, except the dragons, but they're [[{{Ultraterrestrials}} from Earth.]]

Because the different bodies in the solar system are well-understood, don't expect this to show up in hard science fiction, unless you're dealing with some extinct race or ExtremophileLifeforms who can handle the more extreme conditions. In RealLife, astronomers are interested in worlds like Mars and Europa for the potential they may have harbored life, and may still do. It'd almost certainly be microbial, but it would at least show that life is more likely to arise in the universe than previously thought. It's more seen in PlanetaryRomance stories.

The search for life beyond the planet often takes looking beyond the Sun's reach, to distant stars in search for life. But sometimes extraterrestrials are a lot close than even the nearest stars, and you only need to look within the Solar System itself for them. Perhaps the OnceGreenMars still has some greenery, or VenusIsWet. Maybe one of the other moons or planets are inhabited. In short, Earth isn't as lonely as it thinks it is.

* ''Fanfic/RocketshipVoyager'' is ''Series/StarTrekVoyager'' written InTheStyleOf a 1950's sci-fi short story. Earth, Venus and Mars are joined in the Tri-World Federation, designed to give the latter two worlds equal political and military status with humanity so they won't be overwhelmed by an overpopulated and expansionist Earth. Venerians are a primitive matriarchal ProudWarriorRace, while Martians are the equivalent of Vulcans (with some Creator/RayBradbury influence). There are also the (unseen) Jovians who [[ExtremophileLifeforms live in the upper atmosphere of Jupiter]].

* ''Literature/AlanMendelsohnTheBoyFromMars'' features aliens from Mars and Venus, and residents of other solar system planets are mentioned in passing. They're all HumanAliens who are able to use interdimensional travel to planet-hop, and exist largely undetected amidst Earth's general population, who [[LikeRealityUnlessNoted seemingly live on normal 70's Earth]].

* ''Franchise/StarTrek'' of all things. The ''Mego'' toyline had a race of GillMan Neptunians.

** Mercury has Mercurians and from ''ComicStrip/DanDare''.

This is not a case of ColonizedSolarSystem. This is when worlds other than Earth in the Solar System have developed their own form of life. Super-trope of {{Lunarians}}, for extraterrestrials from Earth's own moon, and {{Martians}}, for extraterrestrials from [[UsefulNotes/{{Mars}} the red planet]]. Fictional planets that are inhabited go under CounterEarth.

* ''ComicBook/{{Legion of Super-Heroes}}'': Founding member Imra Ardeen, aka "Saturn Girl" is from Saturn's moon Titan, where the local people all have some degree of telepathy.

** In the ''Hyperborean Cycle'' of short stories, Saturn is known as Cykranosh and is the home of at least one EldritchAbomination. It's [[ArtisticLicenseAstronomy habitable to human visitors]] in "The Door to Saturn", with an ashy surface, liquid metal lakes, and highly diverse inhabitants; the visitors end up living with a race of friendly, toad-like aliens.

* ''ComicBook/TheLeagueOfExtraordinaryGentlemen'' being a MassiveMultiplayerCrossover which treats various [[PlanetaryRomance Planetary Romances]] as canon has a lot of the solar system inhabited;

** The Moon has ''Film/AmazonWomenOnTheMoon'' at war with the [[Literature/TheFirstMenInTheMoon Selenites]] with gravity and air generated by [[Film/TwoThousandAndOneASpaceOdyssey Monoliths]]. [[WesternAnimation/TheClangers The Clangers and the Soup Dragon]] live there as well as [[Literature/TrueHistory Lucien]] and [[Creator/MarvelComics Uatu The Watcher]]
** Venus has [[ComicStrip/DanDare The Treens]]
