This background, according to discoverer Michael Brown, makes the name assigned to the new object entirely appropriate. "The Goddess Eris," said Brown, "created all sorts of problems by causing people to quarrel among themselves. That's exactly what the dwarf planet Eris did as well." Explaining why he and his collaborators had proposed the name to the IAU in the first place, he said simply: "it was just too perfect to pass up."
And the "moon" orbiting UB313 known as S/2005 (2003 UB313)1:
Eris's moon, formerly known by the catchy designation S/2005 (2003 UB313) 1, was also given a name – Dysnomia, who in Greek mythology is Eris's daughter and the Daimon spirit of lawlessness. In addition to the implicit reference to the ongoing controversy, Dysnomia's name is also a nod towards the unofficial nickname by which 2003 UB313 had been known until now – "Xena," the warrior princess of television fame. "Although Xena is now gone from the sky," explained Brown, "we wanted her fans to know that the spirit of Lucy Lawless is still out there." Lucy Lawless is the actress who played Xena on television.
