174567 Varda           Discovered 2003 June 21 by J. A. Larsen at Kitt Peak.
In J.R.R. Tolkien's mythology, Varda is the queen of the stars, the star-kindler. She is the deity who, prior to the birth of the first humans, created the stars and constellations. She also set the vessels of the Sun and Moon upon their appointed courses above the girdle of the Earth. Ilmarë is Varda's handmaid. Ilmarë: Secondary discovered in 2009 by K. S. Noll et al. using the Hubble Space Telescope.
