| 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.

| Paul W. Chodas (1952- ) is a member of the Solar System Dynamics Group at the Jet Propulsion Laboratory. His work has contributed to the understanding of cometary nongravitational forces, the use of radar data in asteroidal and cometary orbits, orbital error analyses, earth close approaches and impact probabilities. He developed the system that allowed the use of radar landmark data on the surface of Venus for improved orbital solutions of the Magellan spacecraft. Citation prepared by D. K. Yeomans, a colleague of the honoree. |
