[edit] Summary

Light curve of the asteroid 201 Penelope based on images taken on 6 October 2006 at Mount John University Observatory.

The bottom scale is in days and one full rotation runs from about -0.14 to 0.02 (or about 3.7 hours). The light curve has two maxima and two minima because 201 Penelope has (to the first order) an ellipsoid shape. It rotates about its short axis, so the minima are when we see it end on, while the maxima are when we see it side on.

Created using Matlab.
