Keelereeglitest

Keelereeglitest, also known as the Keeler Gap, is a prominent feature within Saturn's A ring. It is a 42-kilometer-wide division in the ring system, located approximately 137,700 kilometers from Saturn's center. The gap is named after James Edward Keeler, an American astronomer who first observed it in 1887. Keeler's observations were crucial in understanding the structure of Saturn's rings and the dynamics of planetary ring systems.

The Keeler Gap is maintained by the gravitational influence of the moon Daphnis, which orbits within the gap. Daphnis has a diameter of about 8 kilometers and is responsible for clearing the gap and creating the two narrow, bright edges known as the Keeler Gap Edges. These edges are composed of ring material that has been shepherded by Daphnis into a series of wavy patterns.

The Keeler Gap is a classic example of a gap in a planetary ring system that is maintained by a small moon. Such gaps are important for understanding the dynamics of ring systems and the interactions between moons and rings. The study of the Keeler Gap and its associated features continues to provide valuable insights into the behavior of planetary rings and the processes that shape them.
