Dwarf Planets

The IAU (International Astronomical Union) has spoken. Pluto is no longer a planet. Instead, it is now classified as a Dwarf Planet. Two other objects join Pluto as Dwarf Planets: Ceres, and 2003 UB313 (also called Xena).

This does raise one question. What is Charon, Pluto's former moon? I think Charon had the best name for a moon so I'm sad to see it go into classification limbo. I propose a petition to get the IAU to decide what to do with Charon on the double. It shouldn't be ignored like this.

And what happens to other celestial bodies like Vesta, Pallas and Hygiea. Are they doomed to remain as Asteriods while their big brother Ceres gets all the glory?

This Dwarf Planet thing really opens up a whole can of worms!
