The impactor that formed the Vredefort crater, Earth’s largest, about two billion years ago, was probably much bigger than previously believed—and would have had devastating consequences, a ...

The impactor formed Vredefort crater, what is today the biggest crater on our planet. ... “It is incredibly difficult to constrain the location of landmasses long ago,” Allen says.

A multi-faceted model of Vredefort crater. ... "It is incredibly difficult to constrain the location of landmasses long ago," Allen says.

Previous research put the Vredefort impactor at between 6 to 9 miles in diameter, and the crater — or impact structure as scientists call them — was about 100 to 200 miles across when it was ...

Take the Vredefort crater. If the impact event had occurred 200 million years earlier, then erosion processes would have wiped out the crater by now, according to the new research.

University of the Free StateGeologists and archaeologists are working to examine ancient drawings found in the world’s largest impact crater, Vredefort Crater, in South Africa. A number of ...

The Vredefort crater was birthed 2 billion years ago when the largest asteroid ever to hit Earth impacted the planet. A new study suggests the gargantuan space rock was even bigger than previously ...

The Vredefort crater has eroded over the past 2 billion years, ... “It is incredibly difficult to constrain the location of landmasses long ago,” Allen said.

The Vredefort Crater spans a massive 55 miles in diameter, originally much larger before erosion, and is believed to have been formed by a giant asteroid impact nearly two billion years ago.

An impactor--most likely an asteroid--hurtled toward Earth about two billion years ago, crashing into the planet near present-day Johannesburg, South Africa. The impactor formed Vredefort crater ...

The Vredefort crater, which is located around 75 miles (120 kilometers) southwest of Johannesburg, currently measures about 99 miles (159 km) in diameter, ...

This means the impactor that formed the Vredefort crater would have been larger than the asteroid that killed off the dinosaurs 66 million years ago, forming the Chicxulub crater.
