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).

8217 Dominikhašek           Discovered 1995 Apr. 21 by P. Pravec and L. Sarounova at Ondrejov.
Named in honor of Dominik Hašek (b. 1965), goalkeeper, and the Czech Olympic hockey team, winners of the gold medal at the 1998 Winter Olympic Games in Nagano. Although the success was basically due to teamwork, Hašek's contribution was the most significant. This great win in "the hockey tournament of the century" was widely appreciated by the Czech people and recognized as one of the greatest achievements in the history of Czech sport.
