QUOTE(tractor @ Sep 28 2006, 07:40 AM)  I looked it up... They made it a "dwarf planet" because its oblong rotation around the sun. "planets" have to revole around the sun in a exact circle but pluto was revolving in an oval. I though all planets revolved around the sun in a oval.  Anyway, I am not that bothered about some scientists deciding to remove a planet, as it won't affect me in the slightest, also if they decided it was to remain a planet, we would have hundreds more so call planets. |

Why is Pluto not a planet any more? Some might say it's a dwarf planet. So it should be treated like the rest of the other eight planets. So what if it's smaller than the others it's still there. Ok what if there were nine people including you and you were the smallest. I'm sure you wouldn't want to be left out just because you were small. Most people say the reason why pluto was taken out of the solar system was because they found two new plantes. So they said "what are just going to keep adding more planets or what?" so they toke pluto off. Now thats not fair to pluto.

Yes! Pluto is not a planet anymore since 2006. It is one of the dwarf planets together with Ceres and Eris. Pluto is also a part of the Kuiper Belt Region which is really far away from the sun. There were also some claims that there are still even bigger planets behind pluto..
According to some sources... QUOTE The 2006 definition of "planet" by the International Astronomical Union (IAU) states that in the solar system a planet is a celestial body that: * is in orbit around the Sun, * has sufficient mass so that it assumes a hydrostatic equilibrium (nearly round) shape, and * has "cleared the neighbourhood" around its orbit. A non-satellite body fulfilling only the first two of these criteria is classified as a "dwarf planet", whilst a non-satellite body fulfilling only the first criterion is termed a "small solar system body" (SSSB). The definition was a controversial one, and has drawn both support and criticism from different astronomers. Therefore, Pluto will never be a Planet.

Why would they remove Pluto from being a planet? My only guess is that it is not a planet but just some big spinning ball of ice.
