    Well, wasn't the point of this thread that the currect definition of planet is too broad? I'm just saying criteria that I thought should apply. Shouldn't planets have a stable orbit? Comets orbit around the sun as well, but have a very irregular and large orbit due to their low masses and high speeds.

    You mean the Kuiper (pronounced kai-per) belt?
    And since pluto is part of the kuiper belt (which is essentially just another asteroid belt), doesn't that make it an ateroid? (which is what I think it is)

    Pluto was probably thought of as a planet since it had it's own moon, which is not something that any asteroid or comet can claim.

    Yes, theoretically and object can have a satellite, calling it a moon however, depends on weather you call the mass that said moon orbits, a planet.

    I'd think that both comets and asteroids would have obvious problems at keeping a satellite though.
    As well as having problems with not getting destroyed or (continuously) orbiting the sun.

    the gravity force is the weakest force we know. So, an asteroid wouldn't have enough mass to keep a moon or an object with resonnable dimension.
