Pluto is back, baby

Okay, it's still a dwarf planet, but at least it's back in there. There's two new dwarf planets in the mix too. I particularly like Eris, named for the Greek goddess of discord, with its moon Dysnomia. Must be a freaky little dwarf planet. Or make that big dwarf planet (it's bigger than Pluto and Ceres). The wikipedia entry on these newly classified dwarf planets is pretty funny.
