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]
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.
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 lake was over 130 feet (40 m) deep, and had risen an average of 2.5 feet (0.76 m) each week since the lake was first seen in July 2019. [36] The lake continued to deepen through December 2020 and measured 167 feet (51 m) deep, before the onset of an eruption that began on December 20. [37]
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 ...
40% Engelier: 504 km (313 mi) 34% Gerin: 445 km (277 mi) 30% Gerin is overlain by Engelier Falsaron 424 km (263 mi) 29% Titania (moon of Uranus) Gertrude: 326 km (203 mi) 1,580 km 21% Little of Titania has been imaged, so it may well have larger craters. Pluto (dwarf planet) Sputnik Planitia basin: ca. 1,400 × 1,200 km [8] average: ~1,300 km ...
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.
