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.

6267 Rozhen           Discovered 1987 Sept. 20 by E. W. Elst at Rozhen.
The National Observatory of Bulgaria has been established at Rozhen, not far from the city of Smoljan, close to the Greek border. The observatory, located at a height of 1700 m, profits from excellent instrumental and observational possibilities. In 1986 intensive searches for new minor planets were initiated there.
