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).

6886 Grote           Discovered 1942 Feb. 11 by L. Oterma at Turku.
Named in honor of Grote Reber (b. 1911), pioneer radioastronomer. A radio engineer by profession, he became intrigued by Jansky's 1932 detection of radio waves of extraterrestrial origin. From a series of homemade radio receivers and a 9.4-m parabolic dish antenna in his backyard in Wheaton, Illinois, Reber obtained the first detailed quantitative maps of the radio sky and published these in a series of papers during the 1940s. His stunning results gradually opened the consciousness of others to this very powerful method of observing the universe. Name suggested and citation prepared by G. C. L. Aikman.
