How wide are Saturn’s main rings?

Created from Britannica articles using AI. AI can make mistakes, so verify using Britannica articles.

Saturn’s main ring system is composed of three broad, major rings—the C, B, and A rings—which are visible from Earth. The widths of these specific major rings are as follows:1

  • C ring: 17,500 km1
  • B ring: 25,500 km1
  • A ring: 14,600 km1

While these major rings are separated by gaps and divisions, they collectively span a diameter of approximately 270,000 km (170,000 miles). Despite this vast reach, the rings are remarkably thin, with a thickness that does not exceed 100 meters (330 feet). Beyond these main structures, the entire ring system is much more extensive, spanning nearly 26,000,000 km (16,000,000 miles) when including the faint outer rings.12
