How many asteroid impacts have occurred in the past 600 million years?
Experts and scientist researchers have stated that in the past 600 million years, about 60 asteroids or similar objects of 3 miles or larger in size have hit the earth. Three ground impact events on land have been determined to have caused the mass extinction of life on the planet. There is also known evidence of ocean impacts. Time and again, it has been debated whether ocean impact events could cause a mega tsunami or just a mantle plume (volcanism). The following asteroid impact events created huge craters in the past and may have affected life on earth. First on the list is the massive 118.061-mile radius Vredefort Crater located in Free State, South Africa, which hit 2 billion years ago. Second is the 80.7783-mile radius Sudbury Basin located in Ontario, Canada, which hit 1.8 billion years ago. Third is the 55.9234-mile radius Acraman Crater in South Australia, Australia which hit Earth 580 million years ago. The fourth is the 25-74.5645-mile radius Woodleigh Crater in Western Australia, Australia which hit 360 million years ago. Fifth is the 62.1371-mile radius Manicouagan Crater in Quebec, Canada, which hit 215 million years ago. Sixth is the 43.496-mile radius Morokweng Crater in North West, South Africa, which hit 145 million years ago.
