Xena has been officially renamed Eris, the goddess of strife and discord.
The moon of Eris, formerly known as Gabrielle, is now Dysnomia, the goddess of lawlessness. Mind the pun here: Xena was played by Lucy Lawless!
Eris is not to be confused with Eros, whose actions merely indirectly lead to strife, discord, and children.
Ceres, the largest body in the asteroid belt, has also been given dwarf planet status. A report is found here.
