7	->''"You're not sure how you even landed on the surface of a gas giant. But it's probably best not to think about it for too long..."''
8	-->-- '''EVA report''' from the surface of Jool, ''VideoGame/KerbalSpaceProgram''

10	[[DiscreditedTrope These days]], it's pretty well known that the four largest planets in our solar system lack anything resembling "solid ground” in the conventional sense. The gas giants UsefulNotes/{{Jupiter}} and UsefulNotes/{{Saturn}} are primarily composed of a gassy atmosphere, and the ice giants Uranus and Neptune are mostly a mix of semiliquid methane and water misleadingly called "ices". Although they do have outer cores composed of more solid material (surrounding their molten inner cores), they are not stable surfaces but rather sunken gasses that are under so much pressure from the super-thick atmosphere above that they are forcibly compacted into a firm and often superheated mass. Thus, even if you magically bypassed the unimaginably crushing pressure of the atmosphere, you would be landing on more of a slushy expanse of quicksand than a rocky surface. [[ScienceMarchesOn However, this was not widely understood until the mid-twentieth century]], which has led some sci-fi authors to speculate that there might be solid ground under the cloud layers which might even support life.
11
12	While there are some massive exosolar planets - specifically, the rocky [[https://en.wikipedia.org/wiki/Super-Earth Super-Earths]] and [[https://en.wikipedia.org/wiki/Mega-Earth Mega-Earths]] - that may be capable of sustaining multicellular life, this trope is specifically concerned with gas giants being depicted as having a surface with native life, or at least one capable of supporting visitors.
13
14	A more common, recent adaptation of this trope is having the characters land/live on the rocky ''moon'' of a gas giant-- indeed the concept of terraformed or habitable moons of surface-less gas planets has become quite popular in media and pop culture, and is more scientifically plausible given the discovery of [[https://solarsystem.nasa.gov/moons/jupiter-moons/europa/in-depth.amp liquid oceans on Jupiter’s moon Europa.]] Another common depiction are [[WorldInTheSky floating cities]] in the upper atmosphere of gas giants, as shown by Bespin in ''Film/TheEmpireStrikesBack''.
15
16	If these planets are inhabited, it's SolarSystemNeighbors. Since these planets tend to have higher gravity than Earth their inhabitants tend to be {{Heavy Worlder}}s. However, in some works, this aspect may also be ignored outright, and the high gravity not even mentioned. See OnceGreenMars and VenusIsWet for other [[ScienceMarchesOn discredited]] models of other planets. For gas giant life that doesn't rely on a solid surface try LivingGasbag or FlyingSeafoodSpecial.

20	!!Examples:
21	[[foldercontrol]]
22
23	[[folder:Anime and Manga]]
24	* In ''Manga/DrSlump'', Sioppaman is a superhero assigned to protect Saturn so there are presumably aliens living there.
25	[[/folder]]
26
27	[[folder:Comic Books]]
28	* ''ComicBook/GuardiansOfTheGalaxyMarvelPresents'' depicts Jupiter as having a surface. This is incredibly impossible, so after a few decades, it was changed to mankind having established floating cities on Jupiter, which is also impossible, just not quite as impossible as the previous example.
29	* ''ComicBook/WonderWoman1942'': Neptune evidently has a hard surface and an atmosphere a human can breathe. A few Neptunians try invading earth, only for ComicBook/WonderWoman to overthrow their dictatorship.
30	[[/folder]]
31
32	[[folder:Film -- Live-Action]]
33	* In ''Film/{{Beetlejuice}}'', ghosts who attempt to leave their designated haunting zone are transported to Saturn, which is portrayed as a vast desert populated by {{Sand Worm}}s that attempt to eat them.
34	[[/folder]]
35
36	[[folder:Literature]]
37	* "Call me Joe", by Creator/PoulAnderson, has a traversable Jupiter, except it has no known sapient life. An artificial remotely controlled humanoid is sent to conduct scientific research under the conditions. At one point it is remarked the situation shouldn't exist according to what is known, and no one is certain what the reason is; enough asteroids pulled in to form a solid surface, or a more fundamental error.
38	* ''Literature/CaptainUnderpants'': At the end of ''The Adventures of Super Diaper Baby'', Super Diaper Baby and Diaper Dog get rid of the evil Deputy Doo-Doo by tying him in toilet paper and marooning him on Uranus, which is completely solid (and much smaller).
39	* In "A Conquest of Two Worlds", a Creator/EdmondHamilton short story, one of the titular worlds is Jupiter, with a solid surface and humanoid natives.
40	* In the ''Hyperborean Cycle'' by Creator/ClarkAshtonSmith, Saturn has an ashy surface, liquid metal lakes, and a wide variety of [[SolarSystemNeighbors alien inhabitants]]. Human visitors in the 1932 short story "The Door to Saturn" find it [[NoBiochemicalBarriers perfectly hospitable]] and end up living there.
41	* ''Literature/JohnCarterOfMars'': In the unfinished final book, ''Skeleton Men of Jupiter'', John Carter is taken from Mars to Jupiter. Like Mars, the planet is depicted with a solid surface that even has forests and water, and is inhabited by two sentient races.
42	* ''Literature/LastAndFirstMen'': The Ninth Men are designed to colonize Neptune after the Sixth-Eighth Men's homeworld of terraformed Venus becomes too hot to support life. Despite their HeavyWorlder physiology Nineth Man society collapses quickly but eventually a succession of eight other sapient species evolve from their descendants on Neptune, and the Eighteenth Men are mentioned to use Jupiter and Saturn as agricultural colonies.
43	* ''Literature/{{Micromegas}}'' has a humanoid native of Saturn as one of the characters.
44	* ''Literature/NotFinal'' by Creator/IsaacAsimov. Jupiter has, beneath miles of increasingly thick atmosphere, a solid surface inhabited by a xenophobic alien race who set out to exterminate humanity when they make radio contact with a colony on Ganymede. In the sequel ''Literature/VictoryUnintentional'' a trio of heavily overengineered robots are sent down to Jupiter's surface to ascertain the Jovians' technology, it's under a million Earth atmospheres of pressure at a temperature of -70 degrees Celsius. [[spoiler: Neither the environments nor the Jovians' heat rays phase the robots in the slightest, and the Jovians surrender thinking they were humans.]]
45	* ''Literature/RickyRicottasMightyRobot'': All of the gas giants are depicted as having surfaces and life -- the Jurassic Jackrabbits from Jupiter, the Stupid Stinkbugs from Saturn, the Uranium Unicorns from Uranus, and the Naughty Nightcrawlers from Neptune.
46	* All the planets of the Solar System are habitable in the ''Literature/CaptainFuture'' books, including gas giants (and moons too small to hold atmosphere, but that's a different trope).
47	* In the Creator/CliffordSimak short story, "Desertion" (found in ''City''), Jupiter is a solid planet covered by howling winds. Humans have be transformed into Jovian lifeforms in order to go outside. [[spoiler:And once they do, they never come back...]]
48	* Philip K. Dick sometimes references colonies on Jupiter, Uranus, and Neptune, implying that they are similar to bases on Luna (the Moon) and Mars.
49	* From Creator/RobertAHeinlein:
50	** Strongly implied in ''Literature/TunnelInTheSky'', which refers to the "steel-limbed Jovians" who "enjoy gravity 2.5 times ours" and "poisonous air at inhuman pressure".
51	** "Jovians" are also mentioned in "—We Also Walk Dogs". Neither they nor their homeworld are directly described, but they are described as requiring a high-gravity environment to be comfortable (provided by a centrifuge--or using artificial gravity), but their "apartments" otherwise seem to be rooms with floors and so on, not some kind of tank for living gasbags.
52	** There's a quick mention of "the stations we now have on Pluto, Neptune, and Titan" in ''Literature/BeyondThisHorizon''. Well, two out of three[[note]]worlds with actual solid surfaces that humans could someday conceivably reach[[/note]] ain't bad!
53	* In ''They Fly So High'' by Ross Rocklynne (''Magazine/AmazingStories'' June 1952), two men AbandonShip over Jupiter and are caught in its gravity well. Their pressure-suits with ArtificialGravity protect them as they're falling into the gas giant, until they land on a surface of a strange liquid made solid by surface tension. It's also stated there's a DomedCity somewhere near the Great Red Spot.
54	* A ''WesternAnimation/MuppetBabies'' storybook about the title babies imagining themselves participating in a race for some reason depicted Neptune as having a solid surface.
55	[[/folder]]
56
57	[[folder:Tabletop Games]]
58	* ''Dungeon Magazine'' issue #101 had "Iron Lords of Jupiter", a setting for TabletopGame/D20Modern that was a GenreThrowback to Literature/JohnCarterOfMars-style {{Planetary Romance}}s set on the rocky surface of Jupiter that lay at the core of its enormous atmosphere.
59	* ''TabletopGame/UrbanJungle'': The "Astounding Science" supplement has life on all four giant planets, in homage to its serial and pulp inspirations. Jupiter and Uranus have solid ground beneath their clouds, inhabited by hexapedal felines and silicoid armadillos respectively. While Neptune is a water world with shark people. Saturn might actually be a gas giant but the rings have an envelope of breathable air and dragon-like residents flying between the ice chunks.
60	[[/folder]]
61
62	[[folder:Video Games]]
63	* In ''VideoGame/BlastCorps'', one of the levels takes place on Neptune. It's a "racecourse"-type level where you drive around a rocky track on the surface of the planet.
64	* ''VideoGame/EndlessSpace'': Gas giants can be colonized after researching the appropriate technology. The changes to the gas giants' graphics when they're colonized make it clear that the colonies are on the surface of the gas giant and not orbiting habitats.
65	* ''VideoGame/{{Futurama}}'': The frigging '''SUN''' (which is actually a ''star'', but Administrivia/TropesAreFlexible) is [[ConvectionShmonvection inhabited]]!
66	* ''VideoGame/KerbalSpaceProgram'': Early builds included the ability to land on Jool, the fictional solar system's only gas giant. The "surface" was simply a way for the developers to texture the planet without having to drastically change its code in comparison to other planets. Getting there would even reward the player unique messages from the scientific equipment [[LampshadeHanging lampshading]] the absurdity of the situation, and, of course, the treat of wandering around a featureless green plain. Subsequent versions eventually made it so any spacecraft would [[MadeOfExplodium explode]] under the pressure if they tried to enter Jool’s atmosphere. Even if they somehow make it through, the "surface" has been removed altogether so there isn’t anything to land on.
67	* Averted in ''VideoGame/{{Starbound}}''; you can ''try'', but you'll just get a message from your navigation unit telling you that it's not possible. [[https://steamcommunity.com/sharedfiles/filedetails/?id=1475245421&searchtext=gas+planet Not that it hasn't stopped some enterprising modders from trying...]]
68	** Played straight in the ''VideoGame/FrackinUniverse'' mod, where gas giants are made into a biome that can be landed on thanks to floating islands of SolidClouds and/or asteroids. Functionally, they're similar to ocean planets except with gases instead of liquids.
69	* In ''VideoGame/SolCresta'', every planet you visit is shown as having a solid surface, including Neptune, Uranus, and Saturn. Same with the Sun, as well.
70	* ''VideoGame/StarFlight'': You can ''try'' to land on gas giants, but your ship will immediately be crushed by their strong gravity before you can touch down.
71	* In ''VideoGame/{{Stellaris}}'', one possible scientific anomaly reveals that what your explorers assumed was a gas giant is in fact a rocky, barren world with unusually thick cloud cover. Your astronomers are noted to be deeply embarrassed by the mistake. This could even happen in the Sol System, back before an update that made it so your home system's planets are all automatically surveyed at the game's start.
72	* In ''VideoGame/{{Warframe}}'', most of Neptune's mission nodes are Corpus buildings on top of icy mountains, similar to those seen on Venus and Pluto. No particular explanation is given as to how or why this is the case, though some of the nodes might in fact be on Neptunian moons. Uranus is also depicted as having a massive ocean under its clouds, though Saturn and Jupiter's mission nodes take place on asteroids (presumably in the rings) and floating artificial platforms, respectively.

74
75	[[folder:Western Animation]]
76	* ''WesternAnimation/TheFairlyOddParents'': Jupiter is seen in "[[Recap/TheFairlyOddParentsS8E1LoveTriangle Love Triangle]]", where it's depicted as a rocky, brown surface with mountains. There's even life on it, in the form of a giant, blue {{cyclops}} alien.
77	* ''WesternAnimation/{{Futurama}}'': In [[Recap/FuturamaS3E3ATaleOfTwoSantas "A Tale of Two Santas"]], the Planet Express crew visits the north pole of Neptune to deliver letters to Robot Santa. It's shown to have a breathable atmosphere, covered in solid ice, and inhabited by four-armed Neptunians and Yetis.
78	* ''WesternAnimation/IAmWeasel'': The titular character earned a statue for being the first being that landed on Mars, Jupiter, and Uranus, despite the latter two being a gas giant and an ice giant respectively.
79	* ''WesternAnimation/LooneyTunes'': In the short "Jumpin' Jupiter", Porky Pig and Sylvester are abducted by an alien from Jupiter, and by the end, the pair end up on the surface of what is most likely Jupiter.
80	* When ''WesternAnimation/OscarsOrchestra'' journeys to space in "Star Tours", the instruments are able to land on Jupiter's surface, and even find that it's [[SolarSystemNeighbors inhabited]].
81	* ''WesternAnimation/SpongeBobSquarePants'': In "[[Recap/SpongeBobSquarePantsS8E9MooncationMrKrabsTakesAVacation Mooncation]]", Sandy briefly slides across the rings of Saturn as if they were ice.
82	** In ''WesternAnimation/TheSpongebobMovieSpongeOutOfWater'', Spongebob [[ItMakesSenseInContext accidentally causes Jupiter and Saturn]] to crash into each other, and they both appear to be made of solid rock when they do.
83	* The ''WesternAnimation/{{Fangface}}'' episode "Dr. Lupiter and the Thing from Jupiter" opens with a rocket ship landing on the surface of Jupiter.
84	* One episode of ''WesternAnimation/SuperFriends'' had them strolling on Saturn, with BatmanCanBreatheInSpace in effect as well.
