Mimas: the "Egg-like Moon"
|
Mimas ID:"Mimas is made primarily of water-ice. Its surface is heavily cratered, indicating that its impact features may date back to the time of the moon's creation.
One of the craters, named Herschel, is surprisingly large - nearly one-third the moon's entire diameter. Herschel is 10 Km (about 6 miles) deep, with a central mountain that rises 6 Km (about 3,7 miles) above the crater floor.
Traces of fracture marks can be seen on the opposite side of Mimas.
Mimas was discovered in 1789 by William Herschel; its mean distance from Saturn is approximately equal to 185.520 Km (such as about 115.277 miles); its mass is: 3.81 x 1019 Kg (such as 8.3 x 1019 lbs) and its dimensions are: 418 x 392 x 383 Km (260 x 244 x 238 miles)".
Period of Orbit around Saturn: 22.6 hours
