This is a name of a Transneptunian Object (a plutoid). I think it's quite a lovely name. I think they were originally calling it
Xena, but changed it to much softer
Eris.
Beautiful meaning also: "
Eris is named after the goddess
Eris (Greek Έρις), a personification of strife and discord." Perfect for some peoples' style, albeit it a bit dark. I do like it more than
Iris, which I also like.
