Following hot on the heels of the recent (and to some, heretical) demotion of Pluto to dwarf planet status, and the promotion of Ceres from asteroid to dwarf planet, the International Astronomical Union (via the Central Bureau for Astronomical Telegrams!) has finally seen fit to rename the dwarf planet UB313, more commonly known as Xena:
Following near-unanimous acceptance by the Committee on Small-Body Nomenclature and the Working Group on Planetary-System Nomenclature (in consultation with the discovery team), the IAU Executive Committee has now approved the names Eris for (136199) and Dysnomia for its satellite (136199) Eris I [formerly S/2005 (2003 UB313) . . .
But hold on to your horses! A wing-nut fighting keyboarder has uncovered a liberal plot in choice of the names Eris and Dysnomia.
