  Mimas (moon) - Wikipedia, the free encyclopedia
Mimas (mye'-məs, IPA /ˈmaɪməs/, Greek Μίμᾱς, rarely Μίμανς) is a moon of Saturn that was discovered in 1789 by William Herschel.
Mimas' most distinctive feature is a colossal impact crater 130 km across, named Herschel after the moon's discoverer.
Mimas is responsible for clearing the material from the Cassini Division, the gap between Saturn's two widest rings, A Ring and B Ring.

 Mimas, A Moon of Saturn
During its approach to Mimas on Aug. 2, 2005, the Cassini spacecraft narrow-angle camera obtained multi-spectral views of the moon from a range of 228,000 kilometers (142,500 miles).
This image of Mimas was acquired by the Voyager 1 spacecraft on November 11, 1980 from a range of 425,000 kilometers (264,000 miles).
The diameter of Mimas is 397 kilometers (247 miles), Dione is 1,118 kilometers (695 miles) and Rhea is 1,528 kilometers (949 miles).

 Herschel (crater on Mimas) - Wikipedia, the free encyclopedia
The crater is so large that it is surprising that Mimas was not shattered by the impact that caused it.
It measures 130 km across, covering almost 1/3 of the diameter of the entire moon; its walls are approximately 5 km high, parts of its floor are 10 km deep, and its central peak rises 6 km above the crater floor.
The impact that formed Herschel must have nearly disrupted Mimas entirely; fractures can be seen on the opposite side of Mimas that may be due to the shock waves from the impact travelling through the moon's body.

The moon of Saturn –; Mimas (I) – was discovered was discovered along with Enceladus in 1789, by the same man who only a few years earlier became the famous discoverer of Uranus – W. Herschel.

 The Moons of Saturn
Saturn's other moons have icy surfaces that are very cold so that ice is as rigid as rock and craters form from meteor impacts.
The mean densities of these moons are 1.0 to 1.5 g/cc, implying that they are probably mostly ice, though they may have some rocky consituents.
In various instances now we know that ring structures in the Jovian planets are stabilized by small "shepherd moons" that orbit in or near the rings and stabilize them by their gravitational influences.

 Mimas   (Site not responding. Last check: 2007-10-20)
Mimas was one of the Titans slain by Hercules.
The surface of Mimas is dominated by an impact crater 130 km across, known as Herschel; it's almost 1/3 of the diameter of the entire moon.
This suggests that early in its history, Mimas was probably impacted by even larger bodies than the one that created Herschel which completely disrupted the new moon (wiping out the evidence of earlier large impacts) but that the impact debris then coalesced again to form present-day Mimas.
