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.

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

1952 Hesburgh           Discovered 1951 May 3 at the Goethe Link Observatory, Indiana University.
Named in honor of the Very Reverend Theodore M. Hesburgh, C.S.C., President of the University of Notre Dame since 1952. Father Hesburgh has an extraordinary record of public service in areas ranging from the humanitarian to the technical and scientific. During his 12 years as a member of the National Science Board he played a very important role in the founding of both the Kitt Peak National Observatory and the Cerro Tololo Interamerican Observatory. His support for CTIO during the 1964 period of inflation in Chile was decisive. Name proposed by F. K. Edmondson.
