(9012) Benner Main-belt Asteroid
Discovered on 26 October 1984 by E. Bowell at Anderson Mesa.
Lance A. M. Benner (b. 1964) is a scientist at the Jet Propulsion Laboratory. His hard work and selfless dedication to dozens of radar experiments on minor planets at Goldstone and Arecibo have contributed dramatically to their success. He was the first to realize with certainty that 2000 DP107 is a binary system.Naming citation (20010109/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
