In July 2005, a team from the California Institute of Technology announced the discovery of a possible “tenth planet” temporarily called 2003 UB313. This most distant object so far found in our solar system is just slightly larger than Pluto and takes 560 years to make a very skewed orbit of the Sun. Most planets circle the Sun very near the same plane as Earth’s orbit, but the new object’s orbit is off this elliptic plane by about 44 degrees. Astronomers studying this object nicknamed it “Xena” and in 2006 discovered it had a moon, nicknamed “Gabrielle.”
