Saturn’s System of Rings This Cassini image shows many details of Saturn’s rings. The C ring is so faint that it is almost invisible in this view. At 274,000 km, the outer diameter of the A ring is almost twice the diameter of Jupiter. Saturn is visible through the rings (look near the very bottom of the image), which shows that the rings are not solid. The ring system is so large that Mercury could fit inside the Cassini division.
