Vredfort Impact Crater


Vredefort Impact Crater

The Vredefort crater in South Africa is the circular remnant of an impact that struck Earth about 2 billion years ago. Impact events had decreased in our solar system, but they still occurred occasionally. The original crater was probably about 140 kilometers across, but erosion and sediment cover have reduced the exposed crater to about 80 kilometers in diameter.
