That's why I support designating them as secondary planets. As for comets and asteroids, I don't know that they would have the same dynamic activity without being in hydrostatic equilibrium or geologically differentiated. Ceres is likely more planet-like, and possibly Vesta and Pallas also, which appear to have been spherical only to have had a portion taken off in an impact. It may be far too premature to establish a definitive "hierarchy" in the solar system. Many of the larger spherical moons in the solar system also have a lot in common with the large planets.

This post appeared because of the NASA press release I link to at the bottom. There many moons that are also 'dynamic'. I dare say there will be comets and possibly asteroids too. Pluto's status in the heirarchy of the Solar System has no impact on how interesting it is, or what kind if world we will discover through New Horizon's eyes. Yes it was NASA.

These photos show that Pluto is "a dynamic world" with geology and weather, not just a ball of ice and rock, characteristics that mean Pluto has a lot in common with the other, larger planets.
