These satellites range in size from small on the asteroidal scales, to nearly as large as Saturn's moon Mimas. |
|
The rest of Saturn's moons are named after individual Titans like Enceladus and Mimas. |
|
The authors of the new study used data from the Cassini probe orbiting Saturn to measure the libration of Mimas. |
|
Maybe Mimas is solid, but its core is irregular, like the shape of many asteroids. |
|
Mimas always presents the same face to Saturn, just as the Moon does to Earth. |
|
This is puzzling because Mimas is closer to Saturn than Enceladus, and the Mimantean orbit is much more eccentric than the Enceladean orbit. |
|
The satellites of Saturn, Mimas, Enceladus, Tethys, Dione, Rhea, Titan, Iapetus and Hyperion, present phenomena similar to those of the Galilean satellites of Jupiter. |
