Rare Elliptical Craters Reveal New Clues to Strange Saturn Moons

Rare elliptical craters spotted on two of Saturn’s moons reveal new clues about the age and formation of satellites, according to a new study.

Use of data from NASA’s Cassini Mission, researchers from the Southwest Research Institute (SwRI) have measured elliptical craters on Saturn’s moons Tethys and Dione. While circular craters are fairly common and form under a variety of impact conditions, elliptical craters are rarer and are thought to form from slow, shallow impacts, according to a statement from the SwRI.
