Astrognome Scrapbook Tethys


Tethys was discovered by G. D. Cassini in 1684 and is named after the titan Tethys of Greek mythology.

Tethys is a small moon 1,066 km (662 miles) in diameter that orbits 294,660 km (183,100 miles) from Saturn. This cold, airless and heavily scarred body is very similar to the Saturn moons Dione and Rhea except that Tethys is not as heavily cratered as the other two.
