| 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. |

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.

| 8736 Shigehisa | Discovered 1997 Jan. 9 by T. Kobayashi at Oizumi. |
| Osao Shigehisa (b. 1936) has actively observed variable stars since 1952. An enthusiastic recorder of the activities of Japanese amateur astronomers, he played an important role in compiling a History of Amateur Astronomy in Japan in 1987, as well as a sequel in 1994. |
