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.

8103 Fermi           Discovered 1994 Jan. 19 at Farra d´Isonzo.
Named in memory of the Italian physicist Enrico Fermi (1901-1954), winner of the 1938 Nobel Prize in physics for his demonstration of the existence of new radioactive elements produced by neutron irradiation and for the related discovery of nuclear reactions primed by slow neutrons. A many-sided personality, Fermi has been a star in the heavens of this century's physics, as shown in his studies of nuclear and particle physics. He is the second Italian Nobel laureate in physics, joining Guglielmo Marconi (1909).
