Dione's dark trailing hemisphere and bright leading hemisphere are both visible in this view centered on the moon's anti-Saturn facing side.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Sept. 21, 2008 at a distance of approximately 863,000 kilometers (537,000 miles) from Dione and at a Sun-Dione-spacecraft, or phase, angle of 30 degrees. Image scale is 5 kilometers (3 miles) per pixel.
