This list includes all 60 confirmed impact structures in North America in the Earth Impact Database (EID). These features were caused by the collision of large meteorites or comets with the Earth. For eroded or buried craters, the stated diameter typically refers to an estimate of original rim diameter, and may not correspond to present surface ...
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.

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 ...
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. [3]
The impactors that generated these events are thought to have been much larger than those that created the largest known still existing craters/impact structures on Earth, with the impactors having estimated diameters of ~20–50 kilometres (12–31 mi), with the craters generated by these impacts having an estimated diameter of 400–1,000 ...

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 ...
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.
