4716 Urey           Discovered 1989 Oct. 30 by S. J. Bus at Cerro Tololo.
Winner of the 1934 Nobel Prize in chemistry for his discovery of deuterium, Harold Urey (1893-1981) was also one of the founders of planetary science as we know it today. His classic book The Planets (1952) discussed planetary objects and meteorites in the context of chemical and physical relationships.
