Tethys
In Greek mythology, one of the Titans; a daughter of Uranus and Gaia; and the wife of the sea god Oceanus, by whom she was the mother of over three thousand children: the river gods, oceanids (nymphs of the open sea), and the waves.
| She became the teacher of Hera, goddess of women and marriage. |
| The name Tethys was given to the third satellite of the planet Saturn. |
Tethys
| One of the larger moons of Saturn, discovered in 1684 by the Italian-born French astronomer Giovanni Cassini. It has a diameter of 1,060 km/659 mi and orbits Saturn at an average distance of 295,000 km/183,000 mi with a period (time taken to circle the planet) of 1.89 days. Tethys is heavily cratered, with a notable 400-km/249-mi crater called Odysseus. A 2,000-km/1,243-mi complex of valleys called Ithaca Chasma stretches three-quarters of the way around the moon and may be a crack caused by the same impact that produced Odysseus. Tethys is in the same orbit as two smaller moons, Telesto and Calypso, each about 20–30 km/12–19 mi in size. |
