Pluto

Ok, I was originally going to bitch that Pluto was relabeled as a dwarf planet.

I'm still torn. It's a KBO. It's similar to a comet and an asteroid. But, it's got 3 moons and otherwise has cleared it's neighborhood fairly well. It might also be considered a binary planet with 2 moons. It actually would be considered a comet if it's orbit brought it just a little closer to the sun, since it already sublimates an atmosphere during such time. Whatever.

Here are fun links to keep you occupied.

http://en.wikipedia.org/wiki/Cleared_the_neighbourhood
'Stern, currently leading the NASA New Horizons mission to Pluto, objects to the reclassification of Pluto on the basis that—like Pluto—Earth, Mars, Jupiter and Neptune have not cleared their orbital neighbourhoods either. Earth co-orbits with 10,000 near-Earth asteroids, and Jupiter has 100,000 Trojan asteroids in its orbital path. "If Neptune had cleared its zone, Pluto wouldn't be there," he now says.'
