315012 Hutchings           Discovered 2007 Jan. 20 by D. D. Balam at Mauna Kea.
John Barrie Hutchings (b. 1941) uses observations from the X-ray to the radio regimes to probe intrinsically-luminous stars, X-ray binaries, neutron stars and stellar-mass black holes, and active galactic nuclei and quasars.
