Pluto is still a planemo. A planemo includes all objects of planetary mass and usually size. It does include dwarf planets. A planemo is a PLANEtary Mass Object. See those letters? All moons the size of planets are planemos. So ParadoxPyralvex, Ganymede is a planemo, if you like it that way.

Sorry, I meant that the boundary between dwarf planets and regular ones is not Pluto, but it's Ceres and stuff like that.

people, if you do not understand the issue, why the IAU reclassified it, the other dwarf planets, the definitions of dwarf planet and planet, or what the IAU stands for, please stop being so damn opinionated

ok then. what exactly are these parameters for size and mass?
h1train(Saturday 27th of December 2008 09:55:12 AM)
They are about Ceres' mass and size. We could have the term dwarf planet, but it won't include Pluto - the boundary between dwarf planets and regular planets is not Pluto, Ceres and stuff like that. But if there is an object as vmassive as a planet but the size of an asteroid, it can't be an asteroid.

correct me if i'm wrong, but it sounds like you arbitrarily chose Ceres as the cutoff point. Why?
I'll explain. Pluto cannot be the cut-off point because its mass and size don't allow it to - it is 2/3 the size of our Moon and 1/6 the mass of the Moon. What asteroid is 2000 km across (Pluto is even bigger than that). Ceres, on the other hand, was considered an asteroid in the first place. But it is too big for that, but too small for a planet.
