In the 1960s he studied the photometric properties of the lunar surface as part of the Surveyor and Apollo programs.[3]
Between 1989 and 1993, he has discovered nearly 700 minor planets, and ranks among the Top 30 discoverers in MPC's list.[1] His discoveries including the potentially hazardous asteroid 4581 Asclepius, the numbered asteroid that has made the closest approach to Earth at the time,[3] as well as the near-Earth asteroid 4544 Xanthus, and the main-belt asteroid 6312 Robheinlein, which he named after famous science fiction author, Robert Heinlein.[4] He is also a co-discoverer of the three periodic comets 121P/Shoemaker-Holt, 127P/Holt–Olmstead (discovered with C. Michelle Olmstead), and 128P/Shoemaker-Holt.[5]
