385446 Manwë           Discovered 2003 Aug. 25 by M. W. Buie at Cerro Tololo.
Secondary (385446) I = Thorondor discovered in 2006 by K.S. Noll et al. using the Hubble Space Telescope. In J.~R.~R. Tolkien's mythology, Manwë is foremost among the deities who rule the world. Manwë takes special responsibility for the air and winds. He resides in the Undying Lands across the western ocean from Middle Earth. For intelligence of events in Middle Earth, Manwë relies on the kingdom of eagles led by Thorondor.
