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.

5318 Dientzenhofer           Discovered 1985 Apr. 21 by A. Mrkos at Klet.
Kryštof Dientzenhofer (1655-1722) and his son Kilián Ignác (1689-1751) were among the leading architects and builders in the Bohemian Baroque style. Their churches and monasteries in Prague as well as in the country are still a part of Czech scenery. The name was suggested by J. Ticha.
