Originally set to be the tenth planet from the Sun, Eris's discovery in 2003 led to the ousting of Pluto. Eris (EE-ris) is named after the Greek Goddess of discord and strife, who started a dispute that led to the Trojan war because she was not invited to a wedding. Eris is now the 3rd dwarf planet
from the Sun. Three times as far outside Pluto and slightly larger, Eris also has a moon, Dysnomia.
1. Eris was named 2003 UB313 until its classification.
2. Eris was named so because its discovery caused much strife and discord.
