52387 Huitzilopochtli           Discovered 1993 July 20 by E. W. Elst at the European Southern Observatory.
Huitzilopochtli is an Aztec god associated with the sun. His name, meaning "hummingbird of the south" came from the Aztec belief that the spirits of killed warriors followed the sun through the sky during four subsequent years. Thereafter they were transformed into hummingbirds.
