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.
