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.

6980 Kyusakamoto           Discovered 1993 Sept. 16 by K. Endate and K. Watanabe at Kitami.
Named in memory of Kyu Sakamoto (1941-1985), a popular singer in Japan who was beloved as Kyu-chan. His songs "Let's walk turning our faces upward", "Look up at the stars at night" and others were big hits. The first song (English title "Sukiyaki") became one of the world's bestsellers. This planet also symbolizes the famous trio of which Kyu Sakamoto was a member, with songwriter Rokusuke Ei and pianist Hachidai Nakamura: in Japanese, Roku is 6, Kyu 9 and Hachi 8. Name proposed by the discoverers following a suggestion by T. Sato, A. Fujii and Y. Katagiri.
