Our dwarf planet (the largest discovered so far) now has a name! It has been named Eris. The name, Eris, comes from the Greek goddess of chaos and strife, which is an appropriate name, since our dwarf planet caused so much havoc in the astronomical community. In mythology, Eris caused a quarrel among goddesses that sparked the Trojan War. In real life, the discovery of Eris caused astronomers to demote Pluto to a dwarf planet and change the entire definition of what a planet is.
Our nickname, Xena, is now history, and Eris is the formal name.
