The asteroid that formed the Vredefort crater in South Africa, the largest and oldest impact crater known on Earth, was bigger than previously believed, a new study finds. An apparent crater as big as Ohio has been found in Antarctica. Scientists think it was carved by a space rock that caused the greatest mass extinction on Earth, 250 million years ago. A huge impact crater called the South Pole-Aitken basin lies on the moon’s far side. As far as we know, this bad boy is the largest impact crater in the Solar System, measuring around 1,600 miles in diameter and ranging in depth from 3.9 to 5.1 miles. It is the Moon’s biggest, oldest, and deepest known basin. A study of Greenland's rocks may have turned up something unexpected: the oldest and largest meteorite crater ever found on Earth. Researchers think the crater was formed 3 billion years ago The impactor — most likely an asteroid — formed what is today the biggest crater on the planet. Scientists have widely accepted, based on previous research, that the impact structure, known as the Vredefort crater, was formed by an object about 15 kilometers (approximately 9.3 miles) in diameter that was travelling at a velocity of 15 The Vredefort crater is the largest certified impact crater on Earth. In the present Free State Province of South Africa, what remains of it is more than 300 kilometers (190 mi) from when it was created. It is named after the town of Vredefort, near its center. Although the crater itself has long been worn away, it is known as the Vredefort It is estimated that the crater was created when a meteor of about 5 km diameter struck Earth. The Popigai Crater is one of the most well-preserved impact craters on Earth. Manicouagan Crater The Vredefort impact structure is the biggest confirmed crater on Earth and is roughly 2 billion years old. The original crater was thought to be up to 186 miles (300 km) in diameter, but has .
