RLiegh's Journal: "10th Planet" 68 Miles Larger Than Pluto

Yahoo News has an interesting story on the latest findings on the ice ball discovered last year, that some people are calling our 10th planet (which was previously reported here on slashdot). The article states that according to Hubble, the diameter of UB313 measures 1,490 miles; making it marginally larger than Pluto (which is about 1,422 miles across.). This, in part, is refueling the debate as to what should or should not be considered a planet.

The article also mentions that Michael Brown (a California Institute of technology researcher who happens to be studying UB313) has nicknamed the planet "Xena".
