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.

Orbit Viewer applet originally written and kindly provided by Osamu Ajiki (AstroArts), and further modified by Ron Baalke (JPL).

7146 Konradin           Discovered 1960 Sept. 24 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Named in honor of Konradin Ferrari d´Occhieppo (b. 1907), professor emeritus of astronomy of Vienna University and full member of the Austrian Academy of Sciences, on his forthcoming ninetieth birthday. Well known in Austria as a profound teacher and scientist, he is also a nobleman of extraordinary personal modesty and generosity. He has worked on variable stars, as well as on astrometric and calendrical problems and the history of astronomy. His main interest has been in the astronomical aspects of the Star of Bethlehem, a subject to which he devoted a book and many articles. Name suggested by H. F. Haupt (who prepared the citation) and L. D. Schmadel.
