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 ...
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.
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.
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 Kaali impacts (c. 1500 BC) during the Nordic Bronze Age may have influenced Estonian and Finnish mythology, [5] the Campo del Cielo (c. 2500 BC) could be in the legends of some Native Argentine tribes, [6] [7] while Henbury (c. 2700 BC) has figured in Australian Aboriginal oral traditions.

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.
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 .
Haleakalā is far smaller than many volcanic craters ; there is an excellent chance that it is not extinct, but only dormant; and strictly speaking it is not of volcanic origin, beyond the fact that it exists in a volcanic mountain.
