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.

65100 Birtwhistle | Discovered 2002 Feb. 8 by C. W. Juels and P. R. Holvorcem at Fountain Hills. |
British amateur astronomer Peter Birtwhistle (b. 1958) was measuring positions of comets and NEAs photographically during 1982-1986 and in 2002 began CCD astrometry in Great Shefford, Berkshire. On 2003 Sept. 29 he provided confirmation of 2003 SQ222, whose passage at 84~000 km from the earth is the closest known. |
