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.

Note: If the applet has stopped working because of a recent Java upgrade, here is a possible workaround.
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.

Orbit Viewer applet originally written and kindly provided by Osamu Ajiki (AstroArts), and further modified by Ron Baalke (JPL).

22647 Lévi-Strauss           Discovered 1998 July 26 by E. W. Elst at the European Southern Observatory.
French anthropologist and ethnologist Claude Lévi-Strauss (1908-2009) introduced structuralism as the basis of human perception. Disillusioned with the study of philosophy at the Sorbonne, he went in 1935 to Brazil, where his research on Indian tribes culminated in Tristes Tropiques (1955) and La Pensée Sauvage (1962).
