Less than ten thousand years old, and with a diameter of 100 m (330 ft) or more. The EID lists fewer than ten such craters, and the largest in the last 100,000 years (100 ka) is the 4.5 km (2.8 mi) Rio Cuarto crater in Argentina. [2]
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 ...
A high-relief image of Mimas by Cassini on January 30, 2017. The shapes and the texture of its many overlapping craters can clearly be seen. The Mimantean surface is saturated with smaller impact craters, but no others are anywhere near the size of Herschel. Although Mimas is heavily cratered, the cratering is not uniform.
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.
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 ...
As the trend in the Earth Impact Database for about 26 confirmed craters younger than a million years old shows that almost all are less than two km (1.2 mi) in diameter (except the three km (1.9 mi) Agoudal and four km (2.5 mi) Rio Cuarto), the suggestion that two large craters, Mahuika (20 km (12 mi)) and Burckle (30 km (19 mi)), formed only ...
On December 20, 2020, at 9:30 pm local time, an eruption broke out within Halemaʻumaʻu. The US Geological Survey's Hawaiian Volcano Observatory reported that three vents were feeding lava into the bottom of Halemaʻumaʻu Crater, boiling off the water lake that had been growing since summer 2019 and replacing it with a lava lake.

An impact crater is a depression in the surface of a solid astronomical body formed by the hypervelocity impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, [2] impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain.
