Note: This Java-based orbit viewer will eventually be retired.

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 two-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 is not working, here are some notes that might help.
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.

6869 Funada           Discovered 1992 May 2 by K. Endate and K. Watanabe at Kitami.
Named in honor of Takumi Funada (b. 1932), retired schoolmaster and science teacher who is currently director of Sekizaki Kaisei Kan (Sea and Star Museum) and honorary president of the Oita Astronomical Society. He has greatly contributed to amateur astronomy and has helped popularize astronomy to the public. Also well known as an astrophotographer, he has published several books on astronomy. Name proposed by the discoverers following a suggestion by T. Sato and A. Fujii.
