The rings of Saturn are only about 30 feet (10 meters) thick in most parts of the main rings, other parts however are often up to several kilometers thick. The rings are made of dusty ice, in the form of boulder-sized and smaller chunks that gently collide with each other as they orbit around Saturn. Saturn’s gravitational field constantly disrupts these ice chunks, keeping them spread out and preventing them from combining to form a moon.
