New Planet in our Solar System?

Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, and 2003 UB313?

German astrophysicists have concluded a space body located in the outer reaches of the solar system has a diameter 435 miles (700 kilometers) larger than Pluto, the smallest planet (CNN).

With the pressure to classify Pluto as a Kuiper Belt object, 2003 UB313 being larger, it is possible 2003 UB313 could be added as a ninth planet, and kick Pluto off the list. Interesting times... I just hope they give it a catchy name first.
