Tethys and Rhea – The Ice Sisters
Named after two Titans of Greek mythology, Saturn’s moons Tethys and Rhea can be seen in this incredible view from the Cassini Orbiter spacecraft.
Taken on Oct. 11, 2015, the view looks toward the anti-Saturn sides of Tethys and Rhea from a distance of approximately 708,000 miles.
The two moons appear close together here, but Tethys was about 220,000 miles (360,000 kilometers) farther away from Cassini when the image was captured. That is nearly the distance from Earth to our moon.
