“December 6, 2015. NASA’s Cassini spacecraft captured this view of Saturn’s moon Epimetheus (116 kilometers, or 72 miles across) during a moderately close flyby. This is one of Cassini’s highest resolution views of the small moon. This view looks toward the Saturn facing side of Epimetheus. North on Epimetheus is up. The image was taken in green polarized light with the Cassini spacecraft narrow-angle camera.
The view was acquired at a distance of approximately 22,000 miles (35,000 kilometers) from Epimetheus and at a Sun-Epimetheus-spacecraft, or phase, angle of 28 degrees. Image scale is 697 feet (212 meters) per pixel.”
