Saturn and its spectacular rings, in a natural-color composite of 126 images taken by the Cassini spacecraft on October 6, 2004. The view is directed toward Saturn's southern hemisphere, which is tipped toward the Sun. Shadows cast by the rings are visible against the bluish northern hemisphere, while the planet's shadow is projected on the rings to the left.
Although Saturn’s ring system spans an enormous diameter of approximately 270,000 km (170,000 miles), the rings are remarkably thin. Their vertical thickness typically does not exceed 100 meters (330 feet). While some specific regions of the rings may be as thin as 10 meters (33 feet), the overall structure is characterized by this extreme vertical thinness relative to its vast horizontal extent.123
