saturn's moons what are they called
Although most of Saturn's moons are small, a few such as Titan are very large. Many of Saturn's moons orbit around the edge of the planet's rings. They help to keep the rings in place, just as a shepherd keeps sheep in place. For this reason we call these moons Shepherd Moons.
The A and B rings are separated by the Cassini division, which is a large gap in the rings caused by the gravitational pull of Saturn's moon Mimas. The A ring is the one farther from Saturn, on the outside of the Cassini division. It's a bit darker than the B ring.
