1 AU = 1 Astronomical Unit = 149,597,871 kilometers
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.
