The planet with the largest and most complex ring system is Saturn. The rings of Saturn are made up of ice and rock particles that range in size from microscopic to meter-sized. The rings are divided into several distinct regions, each with its own unique characteristics.
The innermost region of Saturn’s rings is called the D Ring. This region is very dense and is thought to be composed of material that was once part of the moon Phoebe. The D Ring extends from about 5,000 kilometers (3,106 miles) to just under 10,000 kilometers (6,213 miles) from Saturn’s center.
The next region out is called the C Ring. This region is much less dense than the D Ring and consists mostly of small ice particles. The C Ring extends from about 10,000 kilometers (6,213 miles) to 20,000 kilometers (12,427 miles) from Saturn’s center.
Beyond the C Ring lies the B Ring—the brightest and most visible ring inSaturn’s system. Like the C Ring, it consists mostly of small ice particles; however, it also contains a higher proportion of larger rocks than any other ring on Saturn . The BRing extends from about 20 000 kilometers(12 427miles )to 40 000kilometers(24 853miles )fromSaturn ‘scenter .
