Prometheus (86 kilometers, 53 miles across) has just passed – and gravitationally disturbed – some of the fine particulate material in the F ring, creating the sheared gap visible in the inner strands of the ring. This view looks down from about 10 degrees above the ringplane. Prometheus and the rings are sunlit from below. At lower right lies the outermost part of the A ring, which grows suddenly brighter outside of the 42-kilometer (26-mile) wide Keeler gap. The image was taken in visible green light with the narrow angle camera on Aug. 2, 2005 from a distance of approximately 632,000 kilometers (392,000 miles) from Prometheus and at a Sun-Prometheus-spacecraft, or phase, angle of 122 degrees. Image scale is 4 kilometers (2 miles) per pixel.
