Orbit Diagram
Note: Make sure you have Java enabled on your browser to see the applet. This applet is provided as a 3D orbit visualization tool. The applet was implemented using 2-body methods, and hence should not be used for determining accurate long-term trajectories (over several years or decades) or planetary encounter circumstances. For accurate long-term ephemerides, please instead use our Horizons system.

Note: If the applet has stopped working because of a recent Java upgrade, here is a possible workaround.
Orbit Viewer

Additional Notes: the orbits shown in the applet are color coded. The planets are white lines, and the asteroid/comet is a blue line. The bright white line indicates the portion of the orbit that is above the ecliptic plane, and the darker portion is below the ecliptic plane. Likewise for the asteroid/comet orbit, the light blue indicates the portion above the ecliptic plane, and the dark blue the portion below the ecliptic plane.

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.
