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.

84447 Jeffkanipe           Discovered 2002 Oct. 6 by NEAT at Haleakala.
While working on a publication for the fortieth anniversary of Arp's Atlas of Peculiar Galaxies, astronomical author and editor Jeff Kanipe (b. 1953) became interested in a spike extending out of the image of Arp 192 = NGC 3303. This led to its recognition in 2009 as a prediscovery trail of (84447) on 1964 Feb. 19.
