List of impact craters in Europe. This list includes all 41 confirmed impact craters in Europe as listed 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
Gallery: meteorite craters in Australia; Australia’s meteorite craters: 32 major impacts; THE LARGEST IMPACT ZONE from a meteorite ever discovered on Earth has been found in central Australia. But the exact ecological impact – thought to be one giant asteroid which broke in two before slamming into the planet over 300 million years ago
Meteorite collisions should have formed throughout the 4.5 billion-year-long history of Earth, but we have only found impact craters that are less than half of the age of the Earth (2 billion years) and younger. In order to understand how to find very old impact craters, we studied the largest of the oldest preserved impact craters.
Space and Astronomy. Meteors, comets and asteroids have slammed into the earth with a force many times greater than the most powerful nuclear bombs. Sometimes, mass extinction followed. There are roughly 180 known impact craters worldwide and fully a third of them—including some of the biggest—are located in North America.
Approximately 165 million years ago, a large meteorite fell on Earth, some 110 km from Kota in Rajasthan, and formed an unusual crater with a diameter of approximately 10 km.
The Vredefort Crater Study. To find out, the researchers dug into one of the planet’s oldest known impact structures: the Vredefort crater in South Africa. The structure is about 300 kilometers (186 miles) across and was formed about 2 billion years ago when an impactor about 20 kilometers (12.4 miles) across slammed into the planet.
