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.

| 10444 de Hevesy | Discovered 1973 Sept. 30 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels. |
| Hungarian-Swedish physicist George de Hevesy (1885-1966) was awarded the Nobel Prize for chemistry in 1943 for his work on the use of isotopes as tracers in the study of chemical processes. Working with Dirk Coster in Copenhagen in 1923, he discovered the element hafnium. The name was proposed by W. A. Fröger. |
