With its light and dark surface, Iapetus appears almost like a comma punctuation mark or a yin and yang symbol in this Cassini image. See PIA11690 to learn more about the brightness dichotomy on Iapetus. This view looks toward the Saturn-facing side of Iapetus (1471 kilometers, 914 miles across). North on is up and rotated 41 degrees to the right. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on May 12, 2010. The view was acquired at a distance of approximately 1.5 million kilometers (932,000 miles) from Iapetus and at a Sun-Iapetus-spacecraft, or phase, angle of 74 degrees. Image scale is 9 kilometers (6 miles) per pixel.
