An internal ocean's presence implies a strong heat source inside Mimas that turned ice into an ocean. Mimas follows an elliptical orbit around Saturn at an average distance of about 115,000 miles ...
Mimas's low density, 1.15 g/cm 3, indicates that it is composed mostly of water ice with only a small amount of rock, and study of Mimas's motion suggests that it may have a liquid ocean beneath its surface ice. The surface of Mimas is heavily cratered and shows little signs of recent geological activity.
This is a list of named geological features on Mimas, a moon that orbits the planet Saturn. Mimantean features are named after people and places in Arthurian legend or the legends of the Titans . The sole exception to this is Herschel Crater , named after William Herschel , the astronomer who discovered Mimas in 1789.
It has a retrograde orbit and rotates on its axis every 9.3 hours. [87] Phoebe was the first moon of Saturn to be studied in detail by Cassini, in June 2004; during this encounter Cassini was able to map nearly 90% of the moon's surface. Phoebe has a nearly spherical shape and a relatively high density of about 1.6 g/cm 3. [30]
This is Mimas, the smallest of Saturn's major moons. Other than its giant impact crater, scientists thought Mimas was a rather boring piece of cold rock. Now, a new study says Mimas is much more ...
Planetary oceanography, also called astro-oceanography or exo-oceanography, [1] is the study of oceans on planets and moons other than Earth.Unlike other planetary sciences like astrobiology, astrochemistry, and planetary geology, it only began after the discovery of underground oceans in Saturn's moon Titan [2] and Jupiter's moon Europa.

The similarity between Mimas's appearance and the Death Star in Star Wars due to the large size of Herschel has often been noted, both in the press and in NASA/JPL press releases. [ 6 ] [ 7 ] This is a coincidence, however, as the crater's similarities were not discovered until 1980 after Voyager 1 gained line of sight, three years after the ...
The atmosphere is composed of molecular oxygen gas (O 2) produced when ultraviolet light from the Sun interacts with water ice in the rings. Chemical reactions between water molecule fragments and further ultraviolet stimulation create and eject, among other things, O 2 .
