Xena, though the final verdict on whether it is the tenth planet is yet to come.
2003 UB313 is a trans-Neptunian object (TNO) larger than the planet Pluto. It has been described as our solar system's tenth planet by its Mount Palomar-based discovery team, NASA, and some media outlets. The International Astronomical Union (IAU) is scheduled to publish the definition of the term "planet" in early September 2006, which will determine whether or not 2003 UB313 is classified as a planet. Its discoverer, Michael E. Brown, has given it the unofficial name "Xena".
90377 Sedna is a trans-Neptunian object, discovered by Michael Brown (Caltech), Chad Trujillo (Gemini Observatory) and David Rabinowitz (Yale University) on November 14, 2003. At the time of its discovery it was the most distant observed natural solar system body, though this has now been exceeded by 2003 UB313. Sedna is described as a cold planetoid, perhaps as large as two-thirds the size of Pluto.
A Planetoid is the term given to minor bodies orbiting the sun, that are bigger than meteoroids, but smaller than planets.

It's Sedna. It's about 1.5 times further out than Pluto.
