Beyenchime-Salaatin Crater
Beyenchime-Salaatin is an impact crater (astrobleme) in the Russian Far East. It is in diameter and is estimated to be 40 ± 20 million years old (Eocene). The crater is exposed at the surface and is located in the Beyenchime river basin, south of the course of its left tributary, the Beyenchime Salaata The Beyenchime (russian: Беенчиме sah, Бэйэнчимэ) is a river in Yakutia (Sakha Republic), Russia.

Impact Crater
An impact crater is a circular depression in the surface of a solid astronomical object formed by the hypervelocity impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Lunar impact craters range from microscopic craters on lunar rocks returned by the Apollo Program and small, simple, bowl-shaped depressions in the lunar regolith to large, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth. Impact craters are the dominant geographic features on many solid Solar System objects including the Moon, Mercury, Callisto, Ganymede and most small moons and asteroids. On other planets and moons that experience more active surface geological processes, such as Earth, Venus, Europa, Io and Titan, visible impact craters are less common because they become eroded ...
