Eris (Otherwise known as : 2003 UB313 , 136199 Eris and formerly Xena) is the most massive dwarf planet and the 2nd largest dwarf planet in The Solar System . She was discovered in 2005 by the Polomar Observatory which was lead by Michael Brown .
Eris is very annoyed by some dwarf planets because most dwarf planets think that she's male but she's female . The reason as to why others think this is because Eris doesn't have any eyelashes but she done it intentionally but she now realises her fate .
She also hates her moon Dysnomia because she's very annoying .
