There are several lists of meteorite impacts of various types available: Category:Lists of impact craters contains lists on various planets, including Earth by continent; Meteorite falls are observed; Meteorite finds are rocks found on the ground which are geologically identified as meteorites; Meteorite contains lists of the most notable of ...
This list of impact structures (including impact craters) on Earth contains the majority of the 194+ confirmed impact structure given in the Earth Impact Database as of 2024. [1] Alphabetical lists for different continents can be found under Impact structures by continent below.
The Kamchatka superbolide is estimated to have had a mass of roughly 1600 tons, and a diameter of 9 to 14 meters depending on its density, making it the third largest asteroid to impact Earth since 1900, after the Chelyabinsk meteor and the Tunguska event. The fireball exploded in an airburst 25.6 kilometres (15.9 mi) above Earth's surface.
“We have long known that on the young Earth meteorite impacts were both more frequent and, on average, larger than today,” said Andrew Knoll, a Harvard geologist and study co-author.
When a gargantuan space rock, estimated to be the size of four Mount Everests, crashed into Earth more than 3 billion years ago, many may assume that it would have wreaked havoc on a young planet. ...
The evidence of the impact included chemical signatures of the meteorite, small spherical structures formed from rock melted by the impact, and chunks of seabed mixed with other debris churned up ...
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 ...
By studying the composition of meteorites that have landed over the years and the asteroids populating our solar system, astronomers have determined that about 70% of known meteorite impacts came ...
