| 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.

| 37655 Illapa | Discovered 1994 Aug. 1 by C. S. Shoemaker and E. M. Shoemaker at Palomar. |
| Illapa was the thunder or weather god of the Incas. Hailing rain down from the celestial river (the Milky Way), Illapa fed the empire. According to legend, he would crack his sister's water jug with a slingshot, reverberating the echoes of thunder as water spilled forth from the sky, showering the parched lands below. |
