It is named after the town of Vredefort, which is near its centre. The structure's central uplift is known as the Vredefort Dome.
The impact structure was formed during the Paleoproterozoic Era, 2.023 billion (± 4 million) years ago. It is the second-oldest known impact structure on Earth, after Yarrabubba.
