->''"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 so 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) flew past the planetoid in July 2015.

That might have changed when the first clear picture of Pluto taken by ''New Horizons'' [[https://www.nasa.gov/feature/new-horizons-spacecraft-displays-pluto-s-big-heart-0 revealed a large heart formation on its surface]][[note]]currently unofficially named by NASA (the IAU has to approve it) as the [[http://www.theverge.com/2015/7/15/8972271/nasa-new-horizons-new-pluto-image Tombaugh Regio,]] after the discoverer of Pluto, Clyde Tombaugh[[/note]] making it an internet sensation and possibly the most [[{{Moe}} adorable (dwarf) planet ever]]. Indeed [[http://pluto.jhuapl.edu other images from the same spacecraft]] have shown Pluto is far from being a dead world covered with craters, instead having large -for its size- mountains, what seem to be dunes, and complex surface features that show (at least past) geological activity.

[[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''. 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/SgtFrog'' 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: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."
* In RosemaryWells's book and the AnimatedAdaptation of [[http://www.dailymotion.com/video/x17htoz_emilys-first-100-days-of-school_shortfilms "Emily's First 100 Days Of School"]] which has 100 pages which has events related to the number. Was the 8th page, where Emily and her the other students tell how many planets for the Solar System. Pluto is inculuded in it, this was made years before Pluto was no longer a planet.
* Inverted in Fatimah Asghar's poem "[[http://www.poetryfoundation.org/poetrymagazine/poem/250212 Pluto Shits On The Universe]]".
-->My name means hell, bitch. I am hell, bitch. All the cold\\
you have yet to feel. Chaos like a motherfucker.\\

* 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''.

[[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.
* In ''TabletopGame/BleakWorld'' we have the [[FaceHeelTurn Court of Darkness]] who was located on Pluto and was also the first (and so far only) court to be destroyed.

[[folder:Video Games]]
* In ''VideoGame/SuperRobotWarsW'', Pluto has become all but forgotten (foreshadowed in a scene in which [[Anime/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 VideoGame/{{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.
* Averted in ''StarControlII''[[note]]Since the game was created in 1992, when Pluto was still considered a planet[[/note]], even if appears alone without Charon, almost devoid of mineral resources, and just with Fwiffo's ship down there.

* ''WebComic/{{xkcd}}'' [[http://www.xkcd.com/1551/ proposes an unorthodox solution]] by reclassifying it as "''dwarf Pluto''".

* [[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!"

* 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.

* ''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.

[[folder:Real Life]]
* As noted in the intro, Pluto was delisted in 2006 by new standards (new in that before, there were ''no'' standards). In fact, in ancient times, the Sun and Moon were planets, while the Earth was ''not'' a planet, because the word "planet" came from the Greek word for "wanderer" [[note]] Remember, back then Earth is considered the center of the solar system, not the Sun [[/note]]. This was inverted with Ceres: 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. 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. In fact, after the New Horizons flyby of Pluto, [[http://www.kob.com/article/stories/s3852044.shtml#.Vae2UPDdVKb the mayor of Alamogordo, New Mexico immediately declares that Pluto is a planet]]. [[http://www.telegraph.co.uk/news/science/space/11739763/Pluto-I-still-call-it-a-planet-says-head-of-Nasa.html Even the head of NASA says that Pluto is a planet for him]]. 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, UsefulNotes/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 more massive 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.
* Historically, astronomers were only looking for the solar system's ninth planet because they made a mistake when calculating Uranus and Neptune's masses when determining their orbits, and concluded that there was another large object affecting them. When Voyager II allowed astronomers to get an accurate figure of their masses, it turns out that their orbits perfectly account for all of the known planets. So if it hadn't been for that mistake, Pluto likely wouldn't have been discovered until decades later, and there would have been a much smaller gap between Pluto's discovery and the rest of the Kuiper Belt. Ultimately, [[ForWantOfANail the only reason the general public, and even most astronomers, care about Pluto is because of a math error]].
