This is a study to check out the stereo effects of looking at the asteroid Ceres at different rotational positions. These frames are taken from the NASA images at http://www.nasa.gov/multimedia/imagegallery/image_feature_404.html and the quicktime movie listed at the bottom of the page.
From the NASA web site: 
New observations of Ceres, the largest known asteroid,
have revealed that the object may be a "mini-planet," and may contain
large amounts of pure water ice beneath its surface.
The observations by NASA's Hubble Space Telescope also show that Ceres shares
characteristics of the rocky, terrestrial planets like Earth. Ceres' shape is
almost round like Earth's, suggesting that the asteroid may have a rocky inner
core and a thin, dusty outer crust.
Hubble studied Ceres for a full nine-hour rotational period, the most complete
view of the celestial body to date.

I copied various frames from the quicktime movie to see if I could see a stereo effect during the period of revolution: To see the stereo effect, cross your eyes and merge the images; you should see three images, with the stereo in the center. Scan down the three series to see which of the images has the greatest stereo effect.
Comparing the first two frames:
