Xena has been given an official name by the IAU, to replace the nickname honouring the character played by Lucy Lawless. Mike Brown proposed and the IAU accepted the name Eris, after the Greek goddess of discord. He's called the name 'too perfect to resist', since his discovery sparked so much discord. The moon Gabrielle has been renamed Dysnomia after Eris's daughter, the spirit of lawlessness. So the actress no longer has a dwarf planet named after her character, but she does have a moon commemorating herself.
