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.

11759 Sunyaev           Discovered 1960 Sept. 24 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Rashid A. Sunyaev (b. 1943), born in Uzbekistan, has worked in Moscow and at the Max Planck Institute. Co-discoverer of the Sunyaev-Zel'dovich effect, he has directed space missions to study the universe in x-rays, \gamma -rays and the cosmic-microwave radiation. He has also contributed to black-hole theory.
