(9983) Rickfienberg Main-belt Asteroid

Discovered on 19 February 1995 by D. di Cicco at Sudbury.

Trained as an astronomer at Rice and Harvard universities, Richard Tresch Fienberg (b. 1956) became editor of Sky & Telescope in 2000. As the fourth at the helm in the magazine's six-decade history, he says it's a dream job that conflicts with stargazing at his private observatory in New Hampshire.Naming citation (20030501/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
