Mimas, also designated Saturn I, is the seventh-largest natural satellite of Saturn. With a mean diameter of 396.4 kilometres or 246.3 miles, Mimas is the smallest astronomical body known to be roughly rounded in shape due to its own gravity.
Saturn's moon Mimas is known for its uncanny resemblance to the dreaded Death Star in the original "Star Wars" movie. ... alongside Saturn's Enceladus and Titan, and Jupiter's Europa and Ganymede ...
Scientists previously thought Mimas was just a big chunk of ice before NASA’s Cassini mission studied Saturn and some of its 146 moons by orbiting the ringed planet between 2004 and 2017.
An annotated picture of Saturn's many moons captured by the Cassini spacecraft. Shown in the image are Dione, Enceladus, Epimetheus, Prometheus, Mimas, Rhea, Janus, Tethys and Titan. The moons of Saturn are numerous and diverse, ranging from tiny moonlets only tens of meters across to the enormous Titan, which is larger than the planet Mercury.
Astronomers have found the best evidence yet of a vast, young ocean beneath the icy exterior of Saturn’s Death Star lookalike mini moon. The French-led team analyzed changes in Mimas’ orbit ...
The sizes and masses of many of the moons of Jupiter and Saturn are fairly well known due to numerous observations and interactions of the Galileo and Cassini orbiters; however, many of the moons with a radius less than ~100 km, such as Jupiter's Himalia, have far less certain masses. [5]
A past resonance between Jupiter and Saturn may have played a dramatic role in early Solar System history. A 2004 computer model by Alessandro Morbidelli of the Observatoire de la Côte d'Azur in Nice suggested the formation of a 1:2 resonance between Jupiter and Saturn due to interactions with planetesimals that caused them to migrate inward ...
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 ...
