The tenth-closest satellite of Saturn, distance 185 539 km, orbital period 0.942 days; also known as Saturn I. Its axial rotation period is the same as its orbital period. It is 416 × 393 × 381 km in diameter, and was discovered in 1789 by F. W. Herschel. Most of its surface is densely covered with impact craters. One of these, named Herschel, is 139 km across, nearly one-third of the satellite’s diameter, and has a large, high central peak. The impact that caused this crater must have nearly split the satellite apart.
