For sometime I've been worried that we might be losing one of our most elusive and mysterious planets in our lonely little solar system (sarcasm implied). Pluto, they thought she was too small and not round enough...But through the infinate wisdom of the "The International Astronomical Union's Planet Definition Committee" I have nothing to fret about anymore...Here is the rule explaining what qualifies a planet....
"A planet is a celestial body that (a) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (b) is in orbit around a star, and is neither a star nor a satellite of a planet." [full text]
In plain language, if it's round and it orbits the Sun, then it's a planet.
Here is you new list of planets good luck as it will grow exponetially
Mercury, Venus, Earth, Mars, Ceres, Jupiter, Saturn, Uranus, Neptune, Pluto and Charon (a double planet) and 2003 UB313.

I'm only for it if they keep 2003 UB313 named Xena....and if they want to add "Warrior Princess" I'm doubly for it.
Adding Charon as a planet through me
Apparently Ceres used to be conidered a planet back in the 18000's
Back in the 18,000's?!?!?! Hey Buck Rodgers...tell me what were the 17,000's like
