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.

4463 Marschwarzschild | Discovered 1954 Oct. 28 at the Goethe Link Observatory, Indiana University. |
The son of Karl Schwarzschild, Martin was a leader in research on the structure and evolution of stars. He was the first to use a hot-air balloon (Project Stratoscope, 1957) to carry a telescope into the stratosphere to take cleaner pictures of the sun. The name was suggested by F. K. Edmondson. |
