Cruithne (KRU-in-ya) is the Earth's "second moon". The name is Old Irish and refers to the early Picts and their king.

I like the sound of Cruithne. Perhaps not usable, but would fit in a fantasy story. It's apparently male, but I think it sounds better on a girl.
I also like Laniakea a lot. Not usable either, but it's so sweet and soft. The meaning "immeasurable heaven" is gorgeous!

WDYT?
BTW, Pangaea is pretty cool, too.
Does the sea exist
Because of our longing?
