Note: This Java-based orbit viewer will eventually be retired.

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 two-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.

Note: If the applet is not working, here are some notes that might help.
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.

233943 Falera           Discovered 2009 Nov. 21 by J. De Queiroz at Sternwarte Mirasteilas, Falera.
Falera, a municipality in the district of Surselva in the Swiss canton of Graubünden, has a rich culture and history. In 1800 B.C., a settlement was started on the Mutta. This came during the Bronze Age and was very significant in the early development of what today is Switzerland. Falera is the hometown of the discoverer.
