according science writer govert schilling, brown wanted call object lila , after concept in hindu mythology described cosmos outcome of game played brahma. name similar lilah , name of brown s newborn daughter. brown mindful of not making name public before had been officially accepted. had done sedna year previously, , had been heavily criticized. however, no objection raised sedna name other breach of protocol, , no competing names suggested sedna.


he listed address of personal web page announcing discovery /~mbrown/planetlila , in chaos following controversy on discovery of haumea, forgot change it. rather needlessly anger more of fellow astronomers, said webpage had been named daughter , dropped lila consideration.

with dispute resolved, discovery team proposed eris on september 6, 2006. on september 13, 2006 name accepted official name iau. brown decided that, because object had been considered planet long, deserved name greek or roman mythology, other planets. asteroids had taken vast majority of graeco-roman names. eris, whom brown described favorite goddess, had fortunately escaped inclusion. name in part reflects discord in astronomical community caused debate on object s (and pluto s) classification.
