Description
English: Prometheus orbit in F ring.

Prometheus zooms across the Cassini spacecraft's field of view, attended by faint streamers and deep gores in the F ring. This movie sequence of five images shows the F ring shepherd moon shaping the ring's inner edge.

Note that the faint ringlet coincident with the orbit of Prometheus (102 kilometers, or 63 miles across) decreases sharply in brightness behind the moon in its path. The normally twisted-looking F ring core is overexposed in the images, causing its appearance to be more uniform than it usually is.

The images were taken in visible light with the Cassini spacecraft narrow-angle camera on Aug. 11, 2006 at a distance of approximately 2.2 million kilometers (1.4 million miles) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 162 degrees. Image scale is 13 kilometers (8 miles) per pixel.

The original GIF from NASA was converted to Theora OGV format using gifsicle, VirtualDub and ffmpeg2theora at 25 frames per second, shown twice and letterboxed to 440 pixels.
