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.

49700 Mather           Discovered 1999 Nov. 1 by E. W. Elst and S. I. Ipatov at Uccle.
U.S. cosmologist John Mather (b. 1946) led the team that constructed the Cosmic Background Explorer Satellite and was a co-recipient of the 2006 Nobel prize in physics for his role in mapping microwave radiation and understanding the early universe. He is also senior project scientist for the James Webb Space Telescope.
