Its walls are approximately 5 km (3 mi) high, [4] parts of its floor are 10–12 km (6–7 mi) deep, and its central peak rises 6–8 km (3 + 1 ⁄ 2 –5 mi) above the crater floor. [2] If there were a crater of an equivalent scale on Earth it would be over 4,000 km (2,500 mi) in diameter – wider than Canada – with walls over 200 km (120 ...
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.
Mimas's low density, 1.15 g/cm 3, indicates that it is composed mostly of water ice with only a small amount of rock, and study of Mimas's motion suggests that it may have a liquid ocean beneath its surface ice. The surface of Mimas is heavily cratered and shows little signs of recent geological activity.
Elgygytgyn, 18 km (11 mi) Bosumtwi, 10 km (6.2 mi) From between 1 and 10 million years ago. The large but apparently craterless Eltanin impact (2.5 Ma) into the Pacific Ocean has been suggested as contributing to the glaciations and cooling during the Pliocene. [15]
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 ...
The Earth Impact Database is a database of confirmed impact structures or craters on Earth. It was initiated in 1955 by the Dominion Observatory , Ottawa, under the direction of Carlyle S. Beals . Since 2001, it has been maintained as a not-for-profit source of information at the Planetary and Space Science Centre at the University of New ...
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.
Parts of Siberia's landscape is scarred with massive craters that keep turning up. The cause, according to a recent study, could mean more to come. Mysterious exploding craters started turning up ...
