On Tethys’ opposite side is the Ithaca Chasma, a deep canyon that runs the majority of the way around the icy moon.

Here’s how it works. The icy moon Tethys sits above Saturn's rings in this photo captured on May 13, 2017, by NASA's Cassini spacecraft.(Image credit: NASA/JPL-Caltech/Space Science Institute) ...

Tethys was on the far side of Saturn with respect to Cassini here; an observer looking upward from the moon’s surface toward Cassini would see Saturn’s illuminated disk filling the sky.
