Eris,

), with a diameter (1,445 mi/2,317 km) slightly larger than that of Pluto. Taking 560 earth years to circle the sun, Eris is believed to be composed of rock and ice. At aphelion (the most distant point from the sun in Eris's orbit), where the temperature is −405°F; (−243°C;), Eris's surface is covered with highly reflective frozen methane, which forms its atmosphere when it is closer to the sun and the surface temperature is warmer (−360°F;/−218°C;). Eris was discovered on Jan. 5, 2005, by astronomers Mike Brown, Chad Trujillo, and David Rabinowitz, using computer analysis of images taken two years earlier in a survey of the Kuiper belt. It was named for the Greek goddess of strife because its discovery was a catalyst for the reclassification of PlutoPluto,

 as a dwarf planet. Eris is known to have one natural satellite, Dysnomia, named for the daughter of the goddess Eris; the moon is estimated to have a diameter about an eighth that of Eris. Eris and its moon were nicknamed Xena and Gabrielle, respectively, before they were officially named.

Eris

/e'ris/ The Greek goddess of Chaos, Discord, Confusion, and Things You Know Not Of; her name was latinised to Discordia and she was worshiped by that name in Rome. Not a very friendly deity in the Classical original, she was reinvented as a more benign personification of creative anarchy starting in 1959 by the adherents of Discordianism and has since been a semi-serious subject of veneration in several "fringe" cultures, including hackerdom.
