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.

6817 Pest           Discovered 1982 Jan. 20 by A. Mrkos at Klet.
Named for the largest of the three towns, Buda, Pest and Óbuda, that form the modern capital of Hungary. The 125th anniversary of the establishment of Budapest as Hungary's political, cultural and scientific center is being celebrated this year. The University Observatory played a major part in the life of both Pest and Buda, with its buildings dominating the panorama for three-quarters of a century after it was founded in 1780. Since 1921 the headquarters of the Konkoly Observatory has also been located in the city, which provided support for the construction of its large dome.
