The dwarf planet we so fondly call "Xena" now has an official name. Yes, some of you Xena fans might be reacting violently now, but the new and agreed upon name isn't so bad: 136199 Eris, (Eris for short) named after the goddess of discord and chaos. The International Astronomical Union (IAU) agreed last September 13 on the name of this dwarf planet, which is now the second (Pluto was the first) in a newly proposed subcategory of planets.

Let's now take a moment to describe Eris' history:

• Greek goddess of discord and strife
• stirs up jealousy and envy among men
• At the wedding of Peleus and Thetis, Eris got spiteful that she wasn't invited, and hence started a quarrel among the goddesses that eventually led to the Trojan war

Now, Eris' moon (which was jokingly called "Gabrielle" by the Xena fans) also now has an official name of Dysnomia, who, in Greek myth, is the daughter of Eris and the demon-spirit of lawlessness. These names were proposed by Mike Brown on behalf of the rest of his team, who discovered the said heavenly bodies back in October 2003.
