The goddess Eris is most famous for having started the Trojan War after being snubbed at a wedding. Not having been invited with the rest of the gods and goddesses, she tossed a golden apple into the crowd of guests inscribedkallisti, or "for the prettiest." This led to an argument among the goddesses Athena, Hera, and Aphrodite over which deserved the apple. Matters escalated, ultimately leading to war. This seems appropriate for the name of a object which sparked intense debate among astronomers and the general public about the definition of a planet, leading to Pluto getting kicked out of the club amidst vocal protests.
