"Fly me to the 2003 UB313...that doesn't sound right"

Hot off the presses courtesy of Boing Boing:

NASA has apparently discovered a 10th planet circling our Sun.

They've been looking for this for a long time. I really hope they didn't make a mistake. The tentative name is 2003 UB313 (clever, those physicists and astronomers) but if the International Astronomer's Union names it Planet X, I will be so disappointed in them.
