Pan running in his "lane"

Saturn's moon Pan occupies the Encke Gap at the center of this image, which also displays some of the A-Ring's intricate wave structure. Pan is 26 Km (about 16 miles) across.
The two most prominent bright banded features seen on the left side of the image are Spiral Density Waves, which propagate outward through Saturn's Rings. The bright crests represent areas with higher ring particle densities.
The image was taken in visible green light with the Cassini spacecraft narrow-angle camera on Aug. 1, 2005, at a distance of approx. 794.000 Km (about 493.000 miles) from Pan. The image scale is 5 Km (such as 3 miles) per pixel.
