According to Wikipedia , Timothy Bruce Spahr is an American astronomer and prolific discoverer of minor planets. From 2000–2014 he worked at the Center for Astrophysics Harvard & Smithsonian Minor Planet Center. From September 2006 to December 2014 he was the director of Minor Planet Center. He is a co-discoverer of Callirrhoe, a moon of Jupiter, and of Albiorix, a moon of Saturn. He also discovered two periodic comets: 171P/Spahr and P/1998 U4. He is credited by the Minor Planet Center with the discovery of 58 minor planets.
