Orbit Diagram

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.

1604 Tombaugh | \N Observatory. The discovery position was published by C. O. Lampland and K. Newman. |
Named by the Lowell Observatory for Clyde W. Tombaugh, the discoverer of Pluto, on the occasion of a symposium on Pluto, held on the fiftieth anniversary of its discovery, 1980 Feb. 18. Tombaugh marked, during the course of his blink examination, over 4000 minor planets on plates obtained with the 0.33-m photographic telescope during the trans-Saturnian search program at the Lowell Observatory. |
