right, but we are coming toward a consensus definition of "planet". not that any of this matters, as the term itself is not really used for much anymore, anyway, outside of popular astronomy. they're all pretty much circumsolar bodies, and who really cares whether the gas giants are "planets" along with the the rocky core bodies and the KBOs. better for astrophysicists and astronomers to refer to them more specifically by typological class, anyway - Jupiter doesn't fall into the same category, or have the same sort of characteristics, as Mars, after all.
