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.

| 3445 Pinson | Discovered 1983 Mar. 16 by E. Barr at the Anderson Mesa Station of the Lowell Observatory. |
| William Hamet Pinson, Jr. (b. 1919), emeritus professor of geology at the Massachusetts Institute of Technology, is known in particular for his extensive studies of the rubidium-strontium ratio in lunar rocks and soil, tektites, meteorites and meteorite craters. The name was suggested by P. Topalian. |
