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.

4897 Tomhamilton | Discovered 1987 Aug. 22 by E. F. Helin at Palomar. |
Thomas William Hamilton (b. 1939) determined radar and fuel requirements for the Apollo Project. Later he wrote shows (in a dozen languages and also for the deaf) for programmable planetaria, taught astronomy for 32 years and trained students to enter the planetarium field. |
