Bagginses agains. Pfui.

Clear favoritism. Quick perusal of thee asteroid name list turns up
not a single Frodo, Samwise, Gollum, Aragorn, or Gimli. At most
that guy Tolkien. At least we don't yet have a Sauron or Morgoth (not
even Melkor) hanging over our heads. Now. if one of the ones I
occasionally come across were still unnamed... I don't know of
any rules requiring that the mythological names be of actually ancient
origin.
