Act of Creation

January 17, 2007

Prometheus dips into the inner F ring at its farthest point from Saturn in its orbit, creating a dark gore and a corresponding bright streamer. Gores created during previous apoapsis (the name for the farthest point in an orbit) passes, are seen above. The older gores are farther behind the moon in its orbit of Saturn.

This view looks toward the unlit side of the rings from about 31 degrees above the ringplane. Prometheus is 102 kilometers (63 miles) across.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Nov. 1, 2006 at a distance of approximately 1.7 million kilometers (1.1 million miles) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 162 degrees. Image scale is 10 kilometers (6 miles) per pixel.
