The crater has a diameter of roughly , larger than the Sudbury Basin and the Chicxulub crater. This makes Vredefort the largest known impact structure on Earth. If the Wilkes Land crater in Antarctica is an impact crater then it is the largest known at diameter. The Vredefort crater's age is estimated to be 2,023 ± 4 million years. It hit during the Paleoproterozoic era. It is the second-oldest known crater on Earth, a little less than 300 million years younger than the Suavjärvi crater in Russia.

It was originally thought that the dome in the center of the crater was formed by a volcanic explosion, but in the mid 1990s evidence revealed that it was the site of a huge bolide impact, as telltale shatter cones were...
