Meh. Why do we have to cubbyhole everything? The orbital mechanics are the same for a two-pound chunk of ice as they are for Jupiter. Only the scale is different. We could rate things on average density and temperature, but there's such a continuum... I mean, look at us. Earth isn't all solid. We've got a solid crust, a molten midsection, and a presumably solid core. Who knows what kind of weirdo properties other planets have? And why do folks have to get their shorts in such a knot about it? You'd think it was sexuality or something... (YA thing I don't see why people have to get their shorts in a knot about. It is what it is...)
