Moons

Featured Replies

Recently Pluto became a dwarf planet, based on whether it has cleared other matter from the neighborhood of its orbit. Masses too small to be nearly spherical are asteroids, comets or smaller stuff.

 

It seems to me a related naming convention, to signify spherical or not, would communicate important info similar to the dwarf planet title. I believe it will be more important as extremely large telescopes see light; they are likely to find moons.
