Saturn's potato-shaped moon Prometheus is rendered in three
dimensions in this close-up from Cassini. This 3-D view is a
color composite picture made from two different black and white
images that were taken from slightly different viewing angles.
The images are combined so that the viewer's left and right eye,
respectively and separately, see a left and right image of the
black and white stereo pair when viewed through red-blue
glasses. This view looks toward the leading hemisphere of
Prometheus (86 kilometers, or 53 miles across). North on
Prometheus is up and rotated 47 degrees to the right. The end of
Prometheus on the lower right points toward Saturn, and the end
on the upper left points away from the planet. The images were
taken in visible light with the Cassini spacecraft narrow-angle
camera on Dec. 26, 2009. The view was obtained at a distance of
approximately 57,000 kilometers (35,000 miles) from Prometheus
and at a Sun-Prometheus-spacecraft, or phase, angle of 33
degrees. Image scale is 339 meters
