Little is known about the tiny moon Helene other than its size (32 kilometers, or 20 miles) and its status as a Trojan moon of Dione (along with Polydeuces). All three moons share an orbit, but Helene lies 60 degrees … Continue reading →

Calypso is a Trojan moon of Tethys orbiting Saturn 60 degrees behind Tethys. Cassini snapped the best image yet of Calypso on September 23, 2005, revealing a colorful and potato-shaped object. More Information Cassini-Huygens Website Saturn’s Moons section Calypso Information … Continue reading →

Ithaca Chasma is an ancient and gigantic rift cutting across the heavily cratered surface of Tethys. Less surprising than many of the other moons of Saturn, Tethys does have its own mysteries, including bright crater floors, younger plains, and evidence … Continue reading →

Telesto is a Trojan moon of Tethys orbiting Saturn 60 degrees ahead of Tethys. Cassini took the best ever images of this tiny moon on October 11, 2005. More Information Cassini-Huygens Website Saturn’s Moons section Telesto Information Table of Contents … Continue reading →

Out of nowhere emerged a Saturn moon to rival Titan in mystery and activity. Here, suddenly, was an ice world not dead but alive and active, spewing out water ice and oxygen from a youthful surface, creating only the second … Continue reading →

Two of the newest moons discovered by Cassini, Pallene and Methone are tiny worlds that lie between the orbits of Enceladus and Mimas. The image above may or may not show these two moons, but the camera used by Cassini … Continue reading →

Herschel Crater covers nearly a third of the diameter of Saturn’s small moon Mimas, helping it to resemble the Death Star from Star Wars. Some of the most breathtaking images taken by Cassini of Saturn and its rings have included … Continue reading →

The tiny and irregular shaped Epimetheus orbits Saturn with a similar moon called Janus, both of which may have formed when a larger body was broken up during a collision earlier in its history. Because the density of Epimetheus is … Continue reading →

Janus is quite similar to Epimetheus. Both moon share the same orbit and trade places with each other every four years. Janus is heavily cratered and likely very ancient. More Information Cassini-Huygens Website Saturn’s Moons section Janus Information Table of … Continue reading →

The craters on the tiny moon Pandora are muted compared to craters on larger moons because they are filled with collapsed debris. The surface is also covered in fine icy material, perhaps as a result of Pandora’s role as a … Continue reading →
