| 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.

| 55576 Amycus | Discovered 2002 Apr. 8 by the NEAT at Palomar. |
| Amycus was the first centaur to engage in battle with the Lapiths after Eurytus was killed for raping Peirithous' bride Hippodamia. He began the battle by smashing the face of the Celadon with a candelabrum stripped from the inmost wedding shrine. Pelates of Pella killed Amycus by stabbing him with a table leg from a maple tree. |
