Nénar

From Tolkien Gateway

Nénar was a star placed in the skies by Varda Elentári.[1] Its identity is uncertain - there are some indications that Tolkien considered it to be the Elvish name of the planet Neptune, but such a faint object seems out of place among the bright stars named with Nénar in The Silmarillion.[2]
