The deepest crater on Earth is the Vredefort Crater in South Africa. It is about 300 kilometers (190 miles) in diameter and 1.2 kilometers (0.75 miles) deep.

It's important to note that the Vredefort Crater is not perfectly preserved. Erosion has worn down the crater over millions of years, so the current depth is only a fraction of its original depth.

The Vredefort Crater was formed by a massive asteroid impact about 2 billion years ago. It's the largest and oldest known impact crater on Earth.
