Planet Xena Has Moon Called Gabrielle! (Link)

Xena, the possible 10th planet in our solar system, has its own moon, a dim little satellite called Gabrielle, its discoverers reported.

Xena, known formally as 2003 UB313, is nicknamed after the warrior princess of television fame. And its moon Gabrielle is named after Xena's TV travelling companion.

The moon is about 155 miles wide and 60 times fainter than Xena, the farthest-known object in the solar system. It is currently 9 billion miles away from the sun, or about three times Pluto's current distance from the sun.

It takes Xena 560 Earth years to complete one trip around the Sun, compared to Pluto's 250 years!
