Pluto Is Expendable

…and while they were arguing, the Borg came and ate it.

"What is this, a model of Pluto? That planet doesn't even exist anymore, you moron!"
Dr. Doofenshmirtz, Phineas and Ferb

Pluto has become the Butt Monkey of 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! 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 Real Life! A change that will alter the universe! ... Er, well, at least the galaxy... The solar system?

What do you mean Reed Richards Is Useless? What can we alter about the universe that would be a big deal 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, 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. Let's blow it up!

The reason Pluto was downgraded from a planetnote  to a dwarf planet is based on the 2006 formalization of the definitionnote . 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, New Horizons (which was launched in January 2006, seven months before the IAU worked its magic) is on its way to explore the planetoid.

    Anime and Manga 
  • Sailor Moon: 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 became a joke among the Sailor Moon fandom. Ironically, the original 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 Getter Robo Armageddon, when a Negative Space Wedgie 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 Star Blazers/Space Battleship Yamato. When the crew discovers an enemy base on Pluto, they consider using the Wave Motion Gun 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 Hellstar Remina, as the titular Planet Eater Cosmic Horror may eat it first, but then proceeds in a few weeks to eat every other planet in turn (including Jupiter, despite it being much larger than Remina), from outermost to innermost… And then it gets to Earth…
  • In Dragonaut: The Resonance Pluto is destroyed when the Eldritch Abomination Thanotos plows right through it on it's way to Earth.
  • Keroro Gunso 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. She doesn't succeed in the end, and is forgotten.

    Comic Books 
  • In the Our Worlds At War DC Comics miniseries, 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 Legion of Super-Heroes. Although there's been a Crisis Crossover since then, and that version of the Legion isn't the main future any more, so it's probably been quietly forgotten.
  • In DC One Million, 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 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 Dan Dare'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.

    Fan Works 

  • During the climatic caper of Mission: Impossible - Ghost Protocol, the team uses planets in the solar system as their callsigns. Benji, the local Butt Monkey, ends up as Pluto.
  • In Chicken Little, 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.

  • Star Trek: The Next Generation 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 Peter David'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 Red Dwarf. Humanity decides to turn one of the nine planets into a gigantic rubbish dump, with a Eurovision Song Contest style contest deciding the loser. It comes down to a fight between Earth and Pluto. Earth loses, and becomes a literal Crapsack World.
  • In Larry Niven's book 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 Harry Potter and the Order of the Phoenix, 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 Robert A. Heinlein's Have Space Suit – Will Travel.
  • In Perry Rhodan 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 HP Lovecraft's works, as Pluto -also known as Yuggoth- is an outpost of the powerful and devious Mi-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 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."

    Live Action TV 
  • When 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 Lexx, Stanley has the Lexx blow up Pluto, largely because it has been over a season 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.
  • Stargate Atlantis:
    • 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 The Big Bang Theory.
    Sheldon: I like Pluto, therefore, I don't like you.
  • "Did you hear about Pluto? That's messed up!"-Burton "Gus" Guster, Psych.
  • Averted (staggeringly) in the Doctor Who 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.

  • Nellie McKay sings "As far as I'm concerned, Pluto's still a planet" in "Identity Theft", an ode to nonconformity, from the Obligatory Villagers CD.
  • Aesop Rock's "Bring Back Pluto" uses this as its central inspiration.
  • The song "I'm Your Moon" by Jonathan Coulton 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) love song.
  • The astronomers' decision not to consider Pluto a planet is one more reason to disregard Colin Matthews's irreverent appendix to Gustav Holst's The Planets.

  • In Super Robot Wars W, Pluto has become all but forgotten (foreshadowed in a scene in which Boss can't even remember it's name), until it's revealed that the Big Bad'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 Spore, Pluto isn't part of it.
  • In the final battle of Final Fantasy VII (International), among the many planets destroyed in Sephiroth's ridiculously long attack, Supernova, Pluto is the first.
  • Averted in Mass Effect. 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 goes kaboom at the end of Starsiege?
  • In Super Scribblenauts, you get the "Astronomer" merit if you "decorate the sky with every planet in the solar system". Pluto does not count toward this.

  • Chester A. Bum blows up Pluto with nukes in an installment of Atop the Fourth Wall, just to get The Nostalgia Critic 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 That Guy with the Glasses universe. Also when he reviews Sailor Moon, he points out this trope and then proceeds to shoot poor Sailor Pluto.

    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, 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, Neil deGrasse Tyson, 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.
