Theimpact may have been one of dozens of huge asteroids that scientists think hit the Earth during the tail end of the Late Heavy Bombardment period, a major period of impacts that occurred early
Hereare the main asteroid impact craters found on Earth, listed in alphabetical order: Acraman – Located in South Australia, it was formed about 580 million years ago after the collision with a huge asteroid. It has a diameter between 85 and 90 kilometers approximately. It is a complex crater, well eroded and with different elevations

Looking at impact craters on both the Earth and Moon, a team of scientists found that there may have been a sudden increase in big impact events starting around 290 million years ago. At around that time, they think, asteroid impacts became as much as 2.6 times more common.

[Bombardment of Earth’s surface by asteroids six or more miles long likely delayed the accumulation of oxygen in Earth’s atmosphere. This, in turn, likely delayed the development of complex life on the planet, according to new research that included UC Riverside scientists.]
Thenews about the discovery of the world’s largest asteroid impact crater is huge, if true—323-miles-in-diameter huge.. Researchers at University New South Wales (UNSW) believe they’ve
