Mimas' gigantic crater Herschel lies near the moon's limb in this Cassini view. A big enough impact could potentially break up a moon. Luckily for Mimas, whatever created Herschel was not quite big enough to cause that level of disruption. When large impacts happen, they deliver tremendous amounts of energy -- sometimes enough to cause global destruction. Even impacts that are not catastrophic can leave enormous, near-permanent scars on bodies like Mimas (246 miles or 396 kilometers across). Credit: NASA/JPL-Caltech/Space Science Institute
