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.

330 Adalberta (A910 CB)          Discovered 1910-Feb-02 by Wolf, M. at Heidelberg
This planet was alleged to have been discovered 1892 Mar. 18 by M. Wolf at Heidelberg with the provisional designation 1892 X. Only one more position Mar. 20 was obtained, and from the resulting circular elements this object was never observed again. In 1982 R. M. West, C. Madsen, and L. D. Schmadel showed that these observations refer to galactic stars, and that 1892 X does not exist. Later in that year the designation 330 Adalberta was assigned to planet A910 CB, which had earlier been incorrectly identified with 783 Nora, and now newly numbered.
Note: "planet" implies "minor planet"
