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.

4663 Falta           Discovered 1984 Sept. 27 by A. Mrkos at Klet.
Josef Falta (1786-1847) was engineer and cartographer of the Schwarzenberg court in Český Krumlov. In 1831 he drew the first map of the panoramic views from the Kleť look-out tower opened in 1825. The name was suggested by J. Ticha.
