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.

8277 Machu-Picchu           Discovered 1991 Apr. 8 by E. W. Elst at the European Southern Observatory.
Machu-Picchu, "old peak", 2350 meters high, is the site of ancient Inca ruins about 80 km nortwest of Cuzco. When he discovered the nearly intact pre-Columbian ruins, Hiram Bingham thought he had found the "lost city of the Incas", but the building style suggests it was the palace of Pachacuti Inca Yupanqui (c. 1438-1471).
