Interesting facts
  • Tethys has a huge impact crater; Odysseus is about 250 miles in diameter.
  • The albedo (surface brightness) of Tethys is very high, most likely because its gravity pulls in ice particles from Saturn’s E Ring.
  • Tethys shares its orbit with two other small moons.  One orbits 60 degrees ahead of Tethys, while the other trails Tethys by the same angle.
