1. The largest impact crater on Earth, the Vredefort crater in South Africa, is 99 miles (160 km) wide and was likely created about 2 billion years ago, according to NASA's Earth Observatory. The crater has largely eroded, but based on what's left of the rim, scientists have estimated...

Earth has suffered much more catastrophic impacts than that throughout its history, and that spectre haunts our civilization. The Chicxululb impact caused a mass extinction and ended the dinosaurs. The Vredefort Crater in South Africa was excavated two billion years ago by an impactor between 10 ...

The largest impact crater on Earth is Vredefort crater in South Africa. It is 300 kilometers (186 miles) in diameter and the impact that created the crate was 2.2 billion years ago. The second largest impact crater is Sudbury crater in Ontario, Canada. It is 250 kilometers (155 miles) ...
Of the 190 impact locations identified on earth, the largest craters by diameter (80 mi/130 km or greater) are at Vredefort, South Africa; and Chicxulub (off the coast of the Yucatán peninsula), Mexico. Others include Acraman Crater, South Australia; Brent Crater, Ontario; the Chesapeake...
