->''"What is this, a model of Pluto? That planet doesn't even exist anymore, you moron!"''
-->-- '''Dr. Doofenshmirtz''', ''WesternAnimation/PhineasAndFerb''

Pluto has become the ButtMonkey of [[UsefulNotes/TheSolarSystem the solar system]]. Want to get someone's attention? Show that things are serious? That a villain can put his money where his mouth is? Screw the {{status quo|IsGod}}! This time, change is happening, and it's something big! Something cosmic! Something on a large-scale level that would shock the world if it happened in RealLife! A change that will alter the universe! ... Er, well, at least the galaxy... The solar system?

What do you mean ReedRichardsIsUseless? What can we alter about the universe that would be a big deal [[DisSimile without being a big deal]]? It's not like we can blow up a planet...

Wait! What about one of those planets floating around the edge of the solar system? That {{insignificant|LittleBluePlanet}}, dark, icy one with one giant and four minuscule satellites -- no one will miss that. It wasn't even important enough to be called a '''real''' planet. What was its name again?

Never mind. [[SacrificialPlanet Let's blow it up!]]

The reason Pluto was downgraded from a planet[[note]]a word which, prior to 2006, had no formal definition[[/note]] to a dwarf planet is based on the [[http://en.wikipedia.org/wiki/IAU_definition_of_planet 2006 formalization of the definition]][[note]]which itself sparked a lot of still-ongoing controversy and criticism, both within and without the astronomical community, for several reasons that include and go beyond Pluto's reclassification, so beware InternetBackdraft[[/note]]. To qualify, an astronomical body has to have four characteristics: (1) It's in orbit around a star or stellar remnant; (2) it's big enough to be spherical from its own gravity; (3) it's not too big that thermonuclear fusion has begun (in other words, it's not a star); and (4) it has cleared its orbit of all similar-sized objects. When the definition was finalized, it was quickly found that Pluto fails the fourth criterion, as it is very similar in size, composition, and orbit to hundreds of other objects in a region of space called the Kuiper Belt. Ironically, Pluto is still one of the most valuable objects for exploration, since it's the closest Kuiper Belt object and can provide science with information about the solar system's formation. So much so, [[http://en.wikipedia.org/wiki/New_Horizons New Horizons]] (which was launched in January 2006, seven months before the IAU worked its magic) is on its way to explore the planetoid.

[[folder:Anime and Manga]]
* ''Franchise/SailorMoon'': Pluto hasn't exactly had the most comfortable career as a Sailor; it gets lonely guarding the Gates of Time after a few centuries. Pluto's demotion as a planet [[HilariousInHindsight became a joke]] among the ''Sailor Moon'' fandom. Ironically, the original [[Manga/SailorMoon manga]] had a Sailor Ceres among a group of asteroid based Sailors. Like Pluto, Ceres is now considered a dwarf planet (see the Real Life section).
* In ''Manga/GetterRobo Armageddon'', when a NegativeSpaceWedgie gets formed in the final moments of the series, Pluto naturally gets sucked in. This is right after the Getters had just ''destroyed Jupiter and three of its moons with '''THE''' Getter Tomahawk''.
* Averted in ''[[Anime/SpaceBattleshipYamato Star Blazers/Space Battleship Yamato]]''. When the crew discovers an enemy base on Pluto, they consider using the WaveMotionGun on it, but the captain vetoes use of the superweapon because Pluto harbors primitive native organisms which the heroes have no right to destroy. Later in the series, the evil Comet Empire shows off its muscle by destroying the ''Moon''.
* Subverted in ''Manga/HellstarRemina'', as the titular PlanetEater [[EldritchAbomination Cosmic Horror]] may eat it first, but then proceeds in a few weeks to eat ''every other planet in turn'' (including Jupiter, [[OhCrap despite it being much larger than Remina]]), from outermost to innermost… [[FromBadToWorse And then it gets to Earth…]]
* In ''Anime/DragonautTheResonance'' Pluto is destroyed when the EldritchAbomination Thanotos plows right through it on it's way to Earth.
* ''Manga/KeroroGunso'' has a Plutonian native visit Earth in one episode. Her species needs to be remembered to exist, and it's downgraded status is causing them to vanish. [[spoiler:She doesn't succeed in the end, and is forgotten.]]

[[folder:Comic Books]]
* In the ''Comicbook/OurWorldsAtWar'' DC Comics miniseries, Comicbook/{{Brainiac}} manages to take over Pluto, hollow it out, and turn it into a brand new Warworld. All without being noticed by the many and various interstellar agencies on Earth, Darkseid and his lieutenants on Apokolips (somehow relocated to the same solar system by Darkseid's badassery), or Imperiex and his many many miniaturized forms. It apparently stays that way until the 31st century, becoming a plot-point in ''ComicBook/{{Legion Of Super-Heroes}}''. Although there's been a CrisisCrossover since then, and ''that'' version of the Legion isn't the main future any more, so it's probably been [[CanonDiscontinuity quietly forgotten]].
* In ''ComicBook/DCOneMillion'', many of the planets in the solar system have been converted into pleasant living spaces. Pluto, on the other hand, is a maximum-security asylum for the solar system's worst criminals, overseen by the 853rd century's version of Franchise/{{Batman}}.
* In the 2008 Virgin Comics revival of the classic 1950s British space hero ''Dan Dare'', written by Garth Ennis, Pluto is destroyed by a "tamed" black hole controlled by Dare's nemesis, the Mekon. Since the series takes place in the "present" of ComicStrip/DanDare's retroactive alternate history timeline, the destruction may have been a tongue-in-cheek spoof of Pluto's demotion to dwarf planet status in 2006. [[/folder]]

[[folder:Fan Works]]
* Eeloo, {{Expy}} of Pluto in ''VideoGame/KerbalSpaceProgram'', gets a very brief mention in ''Fanfic/TheNextFrontier''; turns out the Kerbals accidentally obliterated it while testing their new AlcubierreDrive.
* In ''FanFic/ShinjiAndWarhammer40K'' Kaworu uses Pluto for a [[spoiler:ColonyDrop on Lilith]].
-->''It wasn't as if anyone would care. Pluto was no longer a planet anyway.''

* During the climatic caper of ''Film/MissionImpossibleGhostProtocol'', the team uses planets in the solar system as their callsigns. Benji, the local ButtMonkey, ends up as Pluto.
* In ''Disney/ChickenLittle'', if you look very closely at the aliens' map of the Solar System, Pluto appears to be the first to be crossed out. The movie was released just one year before Pluto's demotion.

* ''Series/StarTrekTheNextGeneration'' novel ''Before Dishonor'': The Borg '''eat it'''. This "settles the debate," which had gone back and forth three or four times in the last four hundred years.
** And, from Creator/PeterDavid's earlier novel ''Imzadi'', discussing a high powered ground-to-air weapon:
-->"Model I blew up during field testing and destroyed half of Pluto. No one cared--it was a boring planet anyway...I'm kidding, Lieutenant."
* Averted in the novelization of ''Series/RedDwarf''. Humanity decides to turn one of the nine planets into a gigantic rubbish dump, with a EurovisionSongContest style contest deciding the loser. It comes down to a fight between Earth and Pluto. Earth loses, and becomes a ''literal'' CrapsackWorld.
* In Creator/LarryNiven's book ''[[Literature/KnownSpace World Of Ptaavs]]'', Pluto is set on fire by a spaceship's exhaust flame.
* In Roger [=MacBride=] Allen's ''The Ring of Charon'' Pluto is used to create a wormhole to a multisystem to which the Earth was abducted.
* In ''Literature/HarryPotterAndTheOrderOfThePhoenix'', Luna Lovegood fights Death Eaters in a room containing models of several planets. She then uses a Reductor Curse to blow up the model of Pluto as a distraction.
* Turns out there's an alien prison inside Pluto in Creator/RobertAHeinlein's ''Literature/HaveSpaceSuitWillTravel''.
* In ''Literature/PerryRhodan'' universe Pluto got destroyed in 3438 as collateral damage in the final showdown of the series' The Cappins story arc. (One of the more classic examples -- when that issue was printed and sold, nobody had the slightest clue yet that Pluto's status as a planet would be called into question over thirty years later.)
* Averted in Creator/HPLovecraft's works, as Pluto -also known as Yuggoth- is an outpost of the powerful and devious [[SufficientlyAdvancedAlien Mi]]-[[StarfishAliens Go]].
* Averted in a young adult novel titled ''No Passengers Beyond This Point'' in which a little girl views Pluto's demotion as representative of things being unstable and shifting - she's clearly psychologically bugged by it.
* In ''[[Literature/JudyMoody Stink: Solar System Superhero]]'', Stink fails a test about the planets when Judy teaches him the "My Very Educated Mother Just Ate Nine Pizzas" mnemonic to help him remember the name of the planets, blissfully unaware that Pluto has been reclassified. Despite getting all of the other planets right, he gets a big red X on his paper. The, he and a classmate start developing new mnemonics, like "My Very Educated Mother Just Served Us Nothing."

[[folder:Live Action TV]]
* When Series/{{Jessie}} is carrying Emma's model of the solar system (her science fair project), she trips and Pluto falls off. During the judging of the science fair Emma wins, because the judges like that she remembered that Pluto is no longer a planet.
* In the final season of ''Series/{{Lexx}}'', Stanley has the Lexx blow up Pluto, largely because it has been over a season [[MikeNelsonDestroyerOfWorlds since they've blown up any planets, and Lexx is getting antsy]]. They make a game out of it with Stanley having the Lexx 'snipe' Pluto while near Earth; it doesn't require a full-power shot.
* ''Series/StargateAtlantis'':
** Neil [=deGrasse=] Tyson actually appeared as himself in one episode, where Rodney [=McKay=] proceeded to make fun of him.
--->'''[=McKay=]:''' Hey at least I didn't de-classify Pluto from planet status. Way to make all the little kids cry, Neil, that make you feel like a big man?
** Likewise, Dr. Tyson appears in ''Series/TheBigBangTheory.''
-->'''[=Sheldon=]:''' I like Pluto, therefore, I don't like you.
* "Did you hear about Pluto? That's messed up!"-Burton "Gus" Guster, ''Series/{{Psych}}''.
* Averted (staggeringly) in the ''Series/DoctorWho'' episode ''The Sun Makers'', in which the last of humanity in a resource-stripped Solar System are relocated to Pluto, which now has six artificial suns. In the episode's defense, it was broadcast less than ten months before the discovery of Pluto's moon Charon, which revealed how ridiculously small Pluto really was. No excuse for the atrocious grasp of Newtonian mechanics, however.

* [[Music/NellieMcKay Nellie McKay]] sings "As far as I'm concerned, Pluto's still a planet" in [[http://www.youtube.com/watch?v=9JR7xeUE92w "Identity Theft"]], an ode to nonconformity, from the ''Obligatory Villagers'' CD.
* Music/AesopRock's "Bring Back Pluto" uses this as its central inspiration.
* The song "I'm Your Moon" by Music/JonathanCoulton is about this trope in general (and the declassification specifically), from the viewpoint of Pluto's moon Charon. The idea is if Pluto can't be a planet, then Charon and Pluto can just be moons of each other forever... turning the whole thing into a sweet (if bizarre) [[SillyLoveSongs love song]].
* The astronomers' decision not to consider Pluto a planet is [[http://www.classicstoday.com/Classics/ConcertReview_ASPFiles/ViewConcertReview.asp?Action=User&ID=504 one more reason]] to disregard Colin Matthews's irreverent appendix to Gustav Holst's ''The Planets''.

* [[http://www.gocomics.com/inkpen/2009/12/17/ This installment]] of ''ComicStrip/InkPen''.
* [[http://www.garfield.com/comics/vault.html?yr=2011&addr=111127 One of Jon's jokes about]] ''ComicStrip/{{Garfield}}'''s weight is Garfield's stomach replacing Pluto as the ninth planet.

[[folder:Tabletop Games]]
* Referenced by ''TabletopGame/{{Scion}}'' when talking about old Hades/Pluto. Hades isn't a happy camper at the downsize of the planet that uses his name.

[[folder:Video Games]]
* In ''VideoGame/SuperRobotWarsW'', Pluto has become all but forgotten (foreshadowed in a scene in which [[MazingerZ Boss]] can't even remember it's name), until it's revealed that the BigBad's base is there. To make matters worse, one of the penultimate boss' attacks features it skewering the victim so hard they go through the planet and out the other side.
* Though you can find our solar system in ''VideoGame/{{Spore}}'', Pluto isn't part of it.
* In the final battle of ''VideoGame/FinalFantasyVII'' (International), among the many planets destroyed in Sephiroth's ridiculously long attack, Supernova, Pluto is the first.
* Averted in ''Franchise/MassEffect''. It turns out Pluto's moon was really a Mass Relay making Pluto the Sol's system's main space port and first line of defense. Also, as a side effect of defrosting Charon, Pluto's orbit was circularized - that wasn't enough to give Pluto back "planet" status, though.
* Guess what [[spoiler: goes kaboom at the end of]] ''{{VideoGame/Starsiege}}''?
* In ''Super VideoGame/{{Scribblenauts}}'', you get the "Astronomer" merit if you "decorate the sky with every planet in the solar system". Pluto does not count toward this.
* In ''VideoGame/MySims Agents'', some of the planets are represented by decorative objects. Part of the description for Pluto says something like "(Well, ''some'' of us still believe it's a planet...)"
* In {{TAGAP}}'s upcoming third episode, Pluto's declassification from "planet" to "dwarf planet" [[FelonyMisdemeanor really angers its inhabitants]]. They are preparing [[DisproportionateRetribution an invasion]]. Did I mention that they are [[WhatDoYoumeanItWasntMadeOnDrugs Funky]] [[AscendedExtra Green]] [[EverythingIsBetterWithPenguins Penguins]]?
* ''VideoGame/NinthRock'' kicks off with Spencer learning that Pluto has been demoted due to its small size, so he decides to sneak into [[BlandNameProduct MASA]] and find a way to make it bigger.
* One of the story books in ''VideoGame/{{Puppeteer}}'' has Pluto lamenting it's not a planet anymore when the Sun Princess visits the furthest planets.
* Averted in ''[[VideoGame/{{Battlezone1998}} Battlezone 2]]''. The base you are flying to investigate, and where a third of the game takes place, is on Pluto.

[[folder:Web Animation]]
* [[http://www.weebls-stuff.com/onthemoon/On+The+Moon+ep.9/ This episode]] of ''OnTheMoon''.
* In a story from wwwchargesdotcomdotbr in 2006, a man woke up from a four-year coma and his daughter was updating him on pieces of bad news. In the end, he said it was okay because his zodiac sign was ruled by Pluto. She was then thinking about how to explain another bad news.

* ''WebComic/{{xkcd}}'' has a mention:
-->She threw me me out yelling, "You don't say those words. Not in this house." It's been two years. I thought the wounds had healed. But I stand by what I said: Pluto should never have been a planet.
* ''Webcomic/SaturdayMorningBreakfastCereal'' gets in on the act [[http://www.smbc-comics.com/?db=comics&id=788 here.]]
* In ''Webcomic/{{Fans}}'', the first sign of a very dangerous enemy is when it [[http://www.faans.com/index.php?p=1254 eats Charon, Pluto's moon]].
* ''Webcomic/{{Punintended}}'' declares the French as having decided to ditch Pluto [[http://punintended.thecomicseries.com/comics/28/ Plus Tôt.]]
* ''Webcomic/EvilInc'': Galactus stops for breakfast and the only thing on the menu is [[http://evil-inc.com/comic/board-meeting/ Pluto]].

[[folder:Web Original]]
* [[WebVideo/BumReviews Chester A. Bum]] blows up Pluto with nukes in an installment of ''WebVideo/AtopTheFourthWall'', just to get WebVideo/TheNostalgiaCritic to take him seriously. The Critic is unimpressed. (He got more reaction from blowing up Hollywood, Rome and France.) This happened during a "Previously on Atop the Fourth Wall" segment, meaning that the above didn't really happen in the Website/ThatGuyWithTheGlasses universe. Also when he reviews ''Anime/SailorMoon'', he points out this trope and then proceeds to shoot poor Sailor Pluto.
* In a [[http://www.youtube.com/watch?v=jtWPW8yJtgM crossover video]] between Creator/FreddieWong and WebVideo/EpicMealTime, one of the things they add to the shot is some planets in the sky. When Pluto pops up, Freddie says "Pluto ain't a planet! Get that outta there!"

[[folder:Western Animation]]
* ''WesternAnimation/Ben10AlienForce'': An alien EvilOverlord blows it up in a demonstration of what he'll do to Earth if he doesn't get his daughter back. And then the Voices of Alien X argue about its status as a (dwarf) planet. And more importantly ''[[SnapBack it's never rebuilt]]''.
* ''WesternAnimation/PhineasAndFerb'': Doofenshmirtz enters the science fair and ridicules a boy who is entering a model of Pluto (see the quote at the top of the page). The boy's older brother then gives Doofenshmirtz a shiner.
* ''WesternAnimation/TheFairlyOddParents'': The president has a button that blows up "the ''planet''" in case he became inexplicably evil. By the end of the episode, Cosmo pushes the button just because he can. Cue Pluto's destruction.
-->'''Cosmo''': "He said THE planet, he didn't say [[ExactWords which one]]."\\
'''Timmy''': "Who cares? It's Pluto."\\
'''Wanda and Cosmo''': Hey! That's not nice!"\\
'''Cosmo''': That's where I keep my corn!"
* ''WesternAnimation/{{Futurama}}'': Dark matter spill in a penguin sanctuary in Pluto.
* ''WesternAnimation/TeenageMutantNinjaTurtles2003'': Michelangelo eats Pluto. Or the doughnut representing Pluto in Donatello's diagram, at least.
--> '''Mikey''' ''(munching):'' What? It's Pluto. Who cares about Pluto?
* In ''WesternAnimation/MissionHill'', Gus and Wally made a B-grade sci-fi movie in TheFifties about a man from Pluto coming to Earth to get revenge for his planet being blown up.
* In an episode of ''WesternAnimation/BatmanTheBraveAndTheBold'', Comicbook/BlueBeetle fights the Planet Master, who uses various powers thematically linked to the planets of our Solar System, including the "[[AnIcePerson cold of Pluto]]". Blue Beetle protests that Pluto isn't considered a planet anymore. Planet Master's response?
* An episode of ''WesternAnimation/TheReplacements'' has the family playing a mini golf course, where they must hit the ball past some obstacles, among them a rotating windmill of planets that block a hole. Mr. Daring puts his ball which gets deflected by one of the planets. Riley then tells him it was deflected by Pluto, to which he retorts that it is not even a real planet anymore.
* An episode of ''WesternAnimation/QuackPack'' was actually about WesternAnimation/DonaldDuck becoming planet-sized and smashing Pluto to pieces because that's where his nephews (all pretending to be superheroes) are hiding. Also, a brief cameo of [[WesternAnimation/PlutoThePup the ''other'' Pluto]] for extra bonus points.
* In an episode of ''WesternAnimation/{{Smeshariki}}'', resident MadScientist Losyash goes on a hunger strike after learning of Pluto's demotion. Seeing this, the Plutonians cancel their plans to attack Earth in retaliation.
* ''WesternAnimation/{{Sidekick}}'' one episode suggested that Pluto as well as Uranus and Neptune were destroyed before, Eric mentions they only have 6 planets now when Saturn was destroyed by a laser.
* This gets referenced in ''WesternAnimation/{{Metalocalypse}}'' when Pickles is guest-starring on a game show and is asked which celestial body is not longer considered a planet. Pickles, being extremely drunk, guesses the earth instead.
* In "The Planet Name Game" on ''WesternAnimation/TheCatInTheHatKnowsALotAboutThat'', the Cat, Nick and Sally travel into space and name the eight planets. Neither Pluto nor the controversy surrounding it are mentioned. Incidentally, this may be the first series of its type to touch the subject of naming the planets since the 2006 decision.
* In ''WesternAnimation/{{Dogstar}}'', Bob Santino blows up Pluto in order to demonstrate the power of the Santino Laser Cannon. He then offers r to blow up Mars so the sound will reach Earth sooner but is stopped from doing so by Fenwick.

[[folder:Real Life]]
* As noted in the intro, Pluto was delisted in 2006 by new standards (new in that before, there were ''no'' standards).
** However, it's unlikely that Pluto would have been given full planet status in the first place if we'd known as much about the solar system as we do now; not only did we not know about the Kupier Belt at the time, but Pluto was initially thought to be considerably larger than it actually is.
** Inverted with Ceres however. It too was made a dwarf planet (an upgrade from simply being a "large asteroid") because it is the only spherical object in the Asteroid Belt, as with Haumea, Makemake, and Eris since they were all discovered after Pluto was recognized.
*** Ceres was, however, considered a planet when it was first discovered in 1801. As scientists discovered more and more "planets" between Mars and Jupiter, the number of planets in the solar system rose to epic proportions. In the 1840s, Ceres and the rest of the tiny "planets" between Mars and Jupiter were demoted into a new category called "asteroids". And yes, [[HistoryRepeats the similarities to Pluto's demotion]] are obvious.
** Pluto's reclassification has been averted in Illinois and New Mexico (The home state of the man who discovered Pluto), where the state legislatures have passed laws reclassifying Pluto as a planet. However, this has yet to occur in Arizona, where the discovery was made.
* Many people and groups had delisted Pluto before the 2006 decision, most prominently the Hayden Planetarium when it reopened in a new building in 2000. Its director, NeilDeGrasseTyson, has since become a public spokesman in favor of Pluto's non-planethood due to that initial controversy — somewhat ironically and unwillingly since he's an astrophysicist, more concerned with the universe at large.
** A more willing public face of the Pluto Perish movement is astronomer Mike Brown; not only is he actually a planetary astronomer, but he discovered Eris, the Kuiper belt object larger than Pluto that got it demoted in the first place. Brown takes a mildly ironic joy in his role in history; his Twitter handle is @Plutokiller and his autobiography is called "How I Killed Pluto and Why It Had It Coming".
* Due to the distance and size of Pluto, it can be destroyed with little more effect than a visible light in the sky. If we assume for simplicity that blowing up Pluto is inefficient enough that just as much energy goes into light, the energy that reaches the Earth would be roughly what we get from the sun in a fifth of a second. Destroying a true planet would most likely wipe out all life on any of the other planets. This is less about that Pluto is expendable as that it's small and far enough that we don't have to worry about being caught in the cross fire.
