For accurate long-term ephemerides, please instead use our Horizons system.This orbit viewer was implemented using two-body methods, and hence should not be used for determining accurate long-term trajectories (over several years or decades) or planetary encounter circumstances.

2246 Bowell           Discovered 1979 Dec. 14 by E. Bowell at the Lowell Observatory's Anderson Mesa Station.
Named in honor of Edward L. G. Bowell, Lowell Observatory astronomer who has made and who continues to make impressive contributions in many areas of minor-planet astronomy. Following his comprehensive UBV photoelectric photometry of minor planets, he has revived and augmented the Lowell photographic astrometric program and has discovered several new objects. He also does extensive orbital work on minor planets, including the establishment of identifications and the prediction of occultations. Name proposed by B. G. Marsden.
