Yarrabubba
21 in the journal Nature claims the Yarrabubba impact structure in Western Australia, at around 2.2 billion years old, is now the oldest known impact crater. The new study was published online March 1 in the journal Earth and Planetary Science Letters.
What is the most recent crater on Earth?
“Recent” impact craters on Earth are the 100 km wide Popigai Crater in northeast Siberia and the 85 km wide Chesapeake Bay in Virginia, both dated around 35 million years. The 24 km wide Ries impact in Germany was dated to 14 million years.
Where is the largest crater in the United States?
Chesapeake Bay Crater
Only discovered in 1990, the Chesapeake Bay Crater now ranks as the largest in the United States. The crater took so long to find because it’s buried under 1,000 feet of rock beneath the ocean floor of Chesapeake Bay.
Where is the Vredefort crater located?
Vredefort Dome, approximately 120 km south-west of Johannesburg, is a representative part of a larger meteorite impact structure, or astrobleme. Dating back 2,023 million years, it is the oldest astrobleme yet found on Earth. With a radius of 190 km, it is also the largest and the most deeply eroded.

How big was the meteorite that hit Arizona?
Barringer Meteor Crater and Its Environmental Effects. Forty-nine thousand years ago, a large 30 to 50 meter diameter iron asteroid impacted the Colorado Plateau in northern Arizona. The resulting massive explosion excavated 175 million tons of rock, forming a crater nearly a mile wide and 570 feet deep.

How big was the Vredefort meteorite?
300 kilometres
The Vredefort crater, with an estimated diameter of 300 kilometres, is the world’s largest known impact structure. It was created when an asteroid measuring at least 10 kilometres landed on Earth an estimated 2 billion years ago.
When did the Vredefort crater hit Earth?
about two billion years ago
The Vredefort Impact Crater was formed when an asteroid struck Earth about two billion years ago in an area that is now the country of South Africa. At the time of formation, the crater is believed to have been about 300 kilometers across.
Where are most meteorites found on Earth?
deserts
The vast majority of collected meteorites are found in deserts, particularly the cold desert of Antarctica, a huge expanse where conveyor belt-like ice flows deposit space debris in specific areas, and the continent’s white hues allow black meteorites to easily stand out.
Where is the biggest Meteor Crater on Earth?
The Vredefort crater is the largest verified impact crater on Earth, more than 300 kilometres (190 mi) across when it was formed.
What is the biggest crater ever made?
The Vredefort Impact Crater is the largest crater in the world. While the ridge of the crater itself has worn away over time, the base of the formation remains and is known as the Vredefort Dome or the Vredefort Impact Structure.
What is the rarest type of meteorite found on Earth?
Stony Iron meteorites are the rarest type of meteorite, making up about 1 to 2% of all recovered meteorites. Stony Iron meteorites consist of a mixture of rocky silicates and metallic nickel/iron. There are two main groups of stony iron meteorites. Pallasites are composed of olivine crystals set in a nickel-iron matrix.

Crater Vredefort. The largest known crater today is Vredefort in South Africa.
