Ring B is the largest and brightest ring around Saturn.
It orbits the planet at a distance of 55,000 to 70,000 miles (88,000 to 112,000 km).
The B ring is made up of thousands of smaller concentric rings that are so close to each other, they are indistinguishable from each other when viewed from Earth.
B-ring ice particles are light-colored and tightly packed, making the ring seem bright and opaque.
The inner edge of the B ring is the brightest point in the ring system.
The second most obvious ring is A.
It is separated from the B ring by the Cassini division.
Similar in makeup to ring B, ring A simply has fewer particles. It is neither as bright nor as opaque, but it is made of thousands of ringlets.
Within the 8,500-mile (13,600-km) band of the A ring lies the Encke division.
