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.

120643 Rudimandl           Discovered 1996 Sept. 10 by M. Tichy at Klet.
Rudi W. Mandl (1894-1948), Czech-German electrical engineer and amateur astronomer, was interested in gravitational lensing. In 1936 he met Albert Einstein and persuaded him to deal with this problem. Einstein then published Lens-Like Action of a Star By the Deviation of Light In the Gravitational Field.
