| 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.

| 9250 Chamberlin | Discovered 1960 Sept. 24 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels. |
| Named in honor of Alan B. Chamberlin, a senior engineer within the Navigation and Flight Mechanics Section of NASA's Jet Propulsion Laboratory. Since joining the staff at JPL in 1996, Alan has shown his expertise in astronomical observing and celestial mechanics. His research work has centered on the search for gaseous emissions from suspected defunct comets and the uncertainties associated with the close approaches to the earth of the so-called potentially hazardous objects. For the New Millennium Deep Space One spacecraft that was launched on 1998 Oct. 25, Alan is responsible for the ephemeris development for both the mission targets and the two dozen well-observed minor planets that will be used by this spacecraft to navigate autonomously to its targets. |
