Is Eris spherical?
A dwarf planet, by the new definition, is large enough for gravity to force it to a sphere.
Overlooked by many is Ceres, formerly an asteroid, is now also a dwarf planet.
Ceres is the G-ddess of grains, and after Her is named our breakfast Cereal. Extra points if anyone can come up with the connection between Ceres and Pluto (without searching the Internet!)
