The International Astronomical Union (IAU) may adopt Xena as the name for UB 313. Michael Brown of the California Institute of Technology who discovered the planet nicknamed it Xena after the warrior princess of TV fame. He chose Xena because it would be the 10th planet which is "X" in roman numerals.
The 12 planets in our solar system listed in order of their proximity to the sun would be Mercury, Venus, Earth, Mars, Ceres, Jupiter, Saturn, Uranus, Neptune, Pluto, Charon, and Xena (UB313). Pluto's largest moon, Charon; and the asteroid Ceres would be categorized as planets. Pluto would be categorized as both a planet and a pluton. Both Pluto and Charon each are large enough (massive enough) to be spherical. Both bodies independently satisfy the definition of “planet”. The reason they are called a “double planet” is that their common centre of gravity is a point that is located in free space outside the surface of Pluto.
The new definition of a planet: any round object larger than 800 kilometers (nearly 500 miles) in diameter that orbits the sun and has a mass roughly one-12,000th that of Earth. Moons and asteroids will make the grade if they meet those basic tests.
The growing category of "plutons" - Pluto-like objects that reside in the Kuiper Belt, a mysterious, disc-shaped zone beyond Neptune containing thousands of comets and planetary objects.
Plutons are distinguished from classical planets in that they reside in orbits around the Sun that take longer than 200 years to complete (i.e. they orbit beyond Neptune). Plutons typically have orbits that are highly tilted with respect to the classical planets (technically referred to as a large orbital inclination). Plutons also typically have orbits that are far from being perfectly circular (technically referred to as having a large orbital eccentricity). All of these distinguishing characteristics for plutons are scientifically interesting in that they suggest a different origin from the classical planets.

If I'm not mistaken, Charon is what's been considered pluto's moon.
I think they need to name the 10th planet Rupert. I'm just a big Douglas Adams fan.

The person who can prove that they found them has the right to name them.

Actually, they found 3. One is named Xena, one is Charon, and I forgot the other one. It begins with a "C", also.
