Been alot lately -- 45th Anniversary of Yuri Gagarin's historic first manned spaceflight, the 25th Anniversary of the first Shuttle launch, ESA's Venus probe enters orbit of that planet, and Hubble checks "Xena" and finds it's not quite a big as thought -- though still bigger than Pluto.
From Space.com:
"The round world, officially catalogued as 2003 UB313, is about 1,490 miles wide with an uncertainty of 60 miles, according to new observations by the Hubble Space Telescope. Pluto is roughly 1,430 miles (2,300 kilometers) wide."
Previous estimates had it around 1800 miles in diameter.
