Saturn's small moons formed by dust of his rings



Small Moons Take Focus

Saturn has more than 60 moons, including giants like Titan and Enceladus, whole worlds with complex geologies and atmospheres. But embedded in its rings are smaller, stony bodies that are just as mysterious in their own ways. One of the persistent questions is whether the rings themselves are the broken remnants of previous moons. Or maybe these small moons could be built up of the material in the rings.

Cassini's new evidence suggests that the ring moons studied have low densities, which means that they are likely to be formed by gently colliding ring material now loosely interlocked.

Since meetings together, the moons have somewhat complicated stories. Small as they are, these ringmen show grooves and cracks from tidal tensions. They are trapped between Saturn's massive tug and the smaller but more complex gravity trait of many larger moons. All of this feature means that they are heated and pulled apart by the forces surrounding them.
