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.
Mimas's most distinctive feature is a giant impact crater 139 km (86 mi) across, named Herschel after the discoverer of Mimas. Herschel's diameter is almost a third of Mimas's own diameter; its walls are approximately 5 km (3 mi) high, parts of its floor measure 10 km (6 mi) deep, and its central peak rises 6 km (4 mi) above the crater floor.
Hawaii island volcanoes are the most recent evidence of this process that, over 70 million years, has produced the 6,000 km (3,700 mi)-long Hawaiian–Emperor seamount chain. [13] The prevailing view is that the hotspot has been largely stationary within the planet's mantle for much of the Cenozoic Era .
The following craters are officially considered "unconfirmed" because they are not listed in the Earth Impact Database. Due to stringent requirements regarding evidence and peer-reviewed publication, newly discovered craters or those with difficulty collecting evidence generally are known for some time before becoming listed.
New lava flows have inundated much of the crater floor and by 7:30 p.m. about 10 meters (32 feet) depth of new lava had been added to the crater floor. The eruption ended 61 days later on March 7, 2023. [51] Three months after the end of the previous eruption, another eruption began on June 7, 2023. [52]

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 film ...
Pauahi Crater is a volcanic crater measuring 2,000 ft (610 m) long, up to some 1,300 ft (400 m) across, and 300 ft (91 m) deep in Hawaii Volcanoes National Park at It is about 3 mi (4.8 km) from the top of the Big Island of Hawaii's Chain of Craters Road, which follows a "chain" that also includes the Hiʻiaka, Puʻu Huluhulu, Kānenuiohamo, Makaopuhi and Nāpau craters.
