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.

10847 Koch           Discovered 1995 Jan. 5 by F. Borngen at Tautenburg.
The German physician Robert Koch (1843-1910) is the chief founder of the methodology of modern bacteriology. In 1876, he showed that the anthrax bacillus causes an infectious disease. He discovered the tuberculosis and cholera bacilli and studied malaria and sleeping sickness. He won the Nobel prize for medicine in 1905.
