New Planet is bigger then Pluto

"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.

Their research puts more pressure on the International Astronomical Union (IAU) to classify the object as the 10th planet in our solar system.

"UB313 is decidedly larger than Pluto," said University of Bonn Professor Frank Bertoldi, whose team's findings will be published in Thursday's journal Nature.

The object, tentatively named 2003 UB313, is an icy body that lies beyond the planet Neptune."

I've been hearing about a 10th planet for quite a few years now, but I thought I remembered it being called "planet X". I kind of like that better then UB313. That just sounds like a name for a submarine or something.

Sorry to all the school kids out there who have to add one more planet to the list, thus making it that much harder to remember for tests in the future. In order from the sun it looks like it'll be:

Mercury
Venus
Earth
Mars
Jupiter
Saturn
Uranus
Neptune
UB313
Pluto
