Which Saturn ring lies just outside the A ring?

Which Saturn ring lies just outside the A ring? The F ring lies just outside Saturn’s A ring.

The F ring is Saturn’s outermost discrete main ring, positioned roughly 3,000 kilometers beyond the A ring’s outer edge. Between them is the Roche Division, a broad separation that helps distinguish the A ring from the narrow, irregular F ring.

Pioneer 11 discovered the F ring in 1979. Later Voyager and Cassini observations showed that it is not a simple smooth band: it contains a narrow core, strands, clumps, kinks, and apparent braiding. Its rapidly changing structure makes it one of the most dynamic ring systems known.

Prometheus and Pandora are commonly called the F ring’s shepherd moons because they orbit near it and influence its material. However, modern studies suggest Prometheus plays the more important role in confining the ring. The alphabetical names can also confuse readers: working outward through the main rings, the order is C, B, A, then F, followed farther out by the faint G and E rings.
