The oldest impact crater on Earth is also the largest.
Vredefort crater in South Africa, also called the Vredefort Dome, was originally 185 miles (300 kilometers) across, scientists estimate.
A meteorite or asteroid bigger than South Africa’s Table Mountain blasted out the giant crater 2.02 billion years ago.

What is bigger than an asteroid?
Asteroids are rocky and metallic objects that orbit the Sun but are too small to be considered planets. They are known as minor planets. Asteroids range in size from Ceres, which has a diameter of about 1000 km, down to the size of pebbles. Sixteen asteroids have a diameter of 240 km or greater.
What is the size of an average asteroid?
Asteroids range in size from Vesta—the largest at about 329 miles (530 kilometers) in diameter – to bodies that are less than 33 feet (10 meters) across.
Where did the biggest asteroid hit Earth?
Even with erosion, it’s considered one of the largest and best-preserved craters on Earth, with an estimated diameter of 62 miles (100 kilometers). Specs: Located near the Kalahari Desert in South Africa, this crater contained the fossilized remains of the meteorite that created it.
