30934 Bakerhansen           Discovered 1993 Nov. 16 by C. S. Shoemaker and D. H. Levy at Palomar.
Lonny Baker (b. 1942) and Todd Hansen (b. 1950) bring an interest in space to large numbers of people. As the Planetary Society's Global volunteer leader, Baker has formed a network of enthusiasts around the world. Hansen's book Deep Sky and other Enthusiasms gives observers an appreciation for the wonder of deep space.
