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.

6266 Letzel           Discovered 1986 Oct. 4 by A. Mrkos at Klet.
Named in memory of Jan Letzel (1880-1925), Czech architect inspired by the Art Nouveau style and who worked in Japan from 1907 to 1923. He designed the Hiroshima Prefectural Commercial Exhibition Hall in 1915. This building, the most elegant in the city, became world famous as the Genbaku Dome or A-bomb Dome, which was left in ruins as an eternal symbol of the tragedy of Hiroshima on 1945 Aug. 6. Name suggested by J. Ticha.
