NASA announced that the Hubble Space Telescope has successfully measured the “10th Planet” and found it to be 1,490 miles, only slightly larger than its neighbor Pluto at 1,422 miles wide. Planetary Scientist at CalTech Mike Brown led the team that recently discovered the newly nicknamed “Xena.” The measurements were snapped in visible light photos taken Dec. 9 and 10, 2005, and just accepted for publication in the Astrophysical Journal. Thankfully, Brown chose the name Xena over space alien Xenu, who has also recently been in the news.
