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.

14700 Johnreid           Discovered 2000 Jan. 6 by the Lowell Observatory Near-Earth Object Search at the Anderson Mesa Station.
Geologist John Barlow Reid (b. 1940), a teacher for 30 years at Hampshire College, Massachusetts, has studied the earth and moon using isotopic methods. He also developed archeological evidence for slavery migration and the life and health of past populations. The name was suggested by L. A. McFadden and R. Bedell.
