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.

6775 Giorgini           Discovered 1989 Apr. 5 by E. F. Helin at Palomar.
Named in honor of Jon D. Giorgini, who has contributed significantly to radar astrometry of minor planets through the development of an On-Site Orbit Determination software system. This allows radar astrometric measurements to be used immediately to improve a target's orbit, and hence yields ephemerides for pointing, time delay and doppler frequency. Since the system became operational at Goldstone in 1993, there has been an order-of-magnitude improvement in the efficiency with which radar observations can progress. In particular, Giorgini's software was key to the success of the radar imaging of (1620) Geographos in Aug. 1994 and (6489) Golevka in June 1995. Citation prepared by D. K. Yeomans and S. J. Ostro.
