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.

32899 Knigge           Discovered 1994 Aug. 4 by F. Borngen at Tautenburg.
Adolph Freiherr von Knigge (1752-1796) wrote novels, satires, dramas and autographic works, and he tranlated Italian and French authors into German. His best known work is Über den Umgang mit Menschen (1788; also known as Knigge), in which he offers a collection of maxims and precepts for a well-mannered life.
