Mimas
Saturn I
Mimas [MY-mass] is one of the innermost moons of Saturn. Mimas was a Titan who was slain by Hercules. William Herschel discovered the moon in 1789. The surface is icy and heavily cratered.

Mimas
The second innermost satellite of Saturn, discovered by Herschel in 1789. P = 0d.94, R 250 km. Albedo 0.49. It is the perturbations of Mimas and Janus that produce the divisions in Saturn's rings.

Mimas, one of the largest moons of Saturn, shows the scars of billions of years of impacts by rocky debris in this close-up view from the Cassini spacecraft, with Saturn's rings in the background.
Mimas reveals a heavily cratered surface similar to the lunar highlands, but it also possesses one of the largest impact structures (in relation to the satellite's size) in the solar system.

Discovery of Uranus
Herschel's music led him to an interest in mathematics, and hence to astronomy. This interest grew stronger after 1773, and he built some telescopes and made the acquaintance of Nevil Maskelyne.

Mimas is tiny, only 244 miles wide, but it has an enormous crater — a hole one-third as wide as the moon itself probably caused by a meteorite. A peak in the center of the crater is two-thirds the height of Mt.

MIMAS
Mimas is one of larger of the 18 moons of Saturn. It has a diameter of 235 miles (390 km) and it orbits at about 116,000 miles from Saturn.

Next comes Mimas. This is a unique moon because it has a huge crater that covers fully one quarter of its entire surface. It is often thought to look like the "Death Star" from the popular movie and book series Star Wars.
That's because Mimas is bombarded by ice spray from one of Saturn's rings, continuously supplying bright new material on the moon's surface.
Mimas (NASA Thesaurus / NASA SP-7, 1965) A satellite of Saturn orbiting at a mean distance of 186,000 kilometers.
Other moons include small Mimas, some 500 km across, just about as small as a spherical satellites get.
The five larger inner satellites-Mimas, Enceladus, Tethys, Dione, and Rhea-are roughly spherical in shape and composed mostly of water ice. Rocky material may constitute up to 40 percent of Dione's mass.
Particles at the inner edge of the Cassini division are in a one-two resonance with the moon called Mimas---they orbit twice for every one orbit of Mimas.
A ring particle moving in an orbit within the Cassini Division has an orbital period exactly half that of Mimas.
The gap is caused by the gravity of Saturn's moon Mimas. Ring particles orbiting in the gap have what is called a "resonance" with Mimas -- they complete exactly two orbits for every one Mimas makes.
By increasing proximity to Saturn, the middle moons are Iapetus, Hyperion, Titan, Tethys, Dione, Rhea, Enceladus, and Mimas.
In the second image pair, Mimas has moved towards the tip of the F Ring. Rhea, another bright moon, has just emerged from behind Saturn. Prometheus, the closest moon to Saturn, has rounded the F Ring's tip and is approaching the planet.
Small moon Mimas is just touching Saturn's disk near the ring plane at the far right. The shadows of Titan and Mimas have both moved off the right side of the disk. Saturn itself has an equatorial diameter of about 120,000 kilometers.
The moon Mimas displays a large crack 2 km (about 1 mile) deep. Tethys is marked by a crack extending 3/4 of the way around it's circumference.
Some of the names are possibly familiar to you - Pan, Daphnis, Atlas, Prometheus, Pandora, Epimetheus, Janus, Mimas, Methone, Pallene, Enceladus, Tethys, Telesto, Calypso, Dione, Helene, Polydeuces, Rhea, Titan, Hyperion, Iapetus, Kiviuq, Ijiraq, ...
The largest of them, Titan, is the only moon in the Solar System with an atmosphere to speak of. The other moons are mostly chunks of ice and rock. One, called Mimas, has a huge crater in it.

Tethys (named after a Greek sea goddess) and Dione (a daughter of Zeus) Mimas, and Enceladus (son of the god Titan) are the names of four of Saturn's other moons. The planet was named in the 6th century after the Roman god of agriculture.
Saturn's known moons are (from nearest to furthest from the planet): Pan, Atlas, Prometheus, Pandora, Epimetheus, Janus, Mimas, Enceladus, Tethys, Telesto, Calypso, Dione, Helene, Rhea, Titan, Hyperion, Iapetus, and Phoebe.
It was discovered by Cassini in 1675. The period of a particle in Cassini's division is about two-thirds that of Janus, one-half that of Mimas, one-third that of Enceladus, and one-quarter that of Tethys. [H76]

The gaps are produced by the gravitational pull of one or more of Saturn's many moons on the tiny particles in the rings. For the Cassini gap, the moon Mimas is responsible for clearing out any material in the region.
mirror, used on the " frontview " plan, Mimas and Enceladus, the innermost Saturnian moons, were brought to view on the 28th of August and the 17th of September 1789.
