WHAT IS A PLANET?

Astronomers are disagreeing and one proposal would add the largest asteroid and two, now three, Kuiper Belt objects - and probably more. Other astronomers want to kick out Pluto. Meanwhile the extra-solar astronomers are disagreeing about brown dwarfs and super-Jupiters. With possible planets being discovered every week the situation is chaotic.

This is especially relevant today as an object bigger than Pluto has been discovered in a distant orbit.
