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.
Orbit Viewer

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.

15045 Walesdymond           Discovered 1998 Dec. 10 by Spacewatch at Kitt Peak.
William Wales and Joseph Dymond were two young Yorkshire men sent to the shores of Hudson Bay by the Royal Society of London to observe the transit of Venus on 1769 June 3. They stayed for over a year at Fort Prince of Wales, near modern-day Churchill, Manitoba.
