Pluto

Pluto is a planet dwarf planet that is at the edge of the solar system.

Is it a planet?
Until it can stop a meteorite from hitting it, it is a dwarf planet, because if it can't reflect rocks, it's a wimp, and planets aren't wimps. But it is still part of the Solar System. Here are the critera for being a planet:
 * 1) Must orbit around the Sun.
 * 2) Looks circular and not like a chunk of rock and shit.
 * 3) Must not be Pluto.
