The Encke Gap in Saturn's A ring is maintained by the presence of the moon Pan, which shares the gap with several diffuse ringlets.
Irregularities in the inner (left side) edge of the gap result from perturbations caused by Pan as it sweeps through the 325-kilometer (200-mile) wide lane.
This view looks toward the sunlit side of the rings from about 38 degrees below the ringplane.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on May 10, 2008. The view was acquired at a distance of approximately 264,000 kilometers (164,000 miles) from Saturn. Image scale is 1 kilometer (0.6 mile) per pixel.
