Pluto is Bigger Than Ceres
I think Ceres should be granted Planet status and possibly Vesta however on the basis of spherical shape. I think that the gravity/size argument Justin mentioned should apply to planets and Moons. I can't wait for the mission visting both and hope Pluto still gets visited. It will help make clear whether these are just plantoid relics or evolved bodies worth status as a planet. Pure size makes no sense as there is obviously a potential continueum.
