Our solar system's newest dwarf planet, formerly nicknamed "Xena", is now officially dubbed Eris, after the Greek goddess of discord, a source of strife and conflict. How appropriate, considering the media frenzy and public outcry over the change in poor li'l Pluto's status, and the scientists redefining of what makes a planet a planet (or, indeed, a dwarf planet). The discovery of Eris set the whole fuss in motion.
The discoverer, Dr Michael E Brown, reckons that the original nod to the Lucy Lawless television series, "Xena: Warrior Princess", remains - since Eris's moon (originally nicknamed "Gabrielle") is now officially named Dysnomia, after the Greek goddess of lawlessness.
But hey, a "Star Trek" connection is even more fun than a "Xena" connection!
ST VI: The Undiscovered Country's Vulcan turncoat, Lieutenant Valeris, was named by actress Kim Cattrall (who wanted simply Eris, after the goddess) and director Nick Meyer (who added the Val- prefix). The final shooting script for ST VI actually spells the name "Val'eris", although not the closing credits. (And the earlier draft scripts, of course, called her Saavik.)
