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).

131763 Donátbánki           Discovered 2002 Jan. 11 by K. Sárneczky and Z. Heiner at Piszkéstető.
Donát Bánki (1859-1922) was a Hungarian mechanical engineer, coinventor of the carburetor in 1893. In 1898 he invented the high-compression engine with a dual carburetor. Some sources say that the idea of the carburetor came from a flower-girl, sprinkling water onto her flowers by blowing spray from her mouth.
