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.

134348 Klemperer           Discovered 1992 Oct. 31 by F. Börngen at Tautenburg.
Victor Klemperer (1881-1960), son of a rabbi, was a professor of philology in Dresden. Suspended, he kept a diary from 1933 to 1945 that is a unique day-to-day account of life under the Nazi tyranny. It was translated into English and filmed.
