South Africa.
The largest crater on Earth is Vredefort Crater, and it measures 99.41 miles across or 160 kilometers. The crater is located in present-day South Africa.

Where are the biggest craters on Earth?
South Africa
About 2 billion years ago, an impactor hurtled toward Earth, crashing into the planet in an area near present-day Johannesburg, South Africa, and forming the Vredefort crater – the biggest and oldest terrestrial impact crater known so far.
What are the 2 largest craters on Earth?
There are more than forty craters of such size. The largest two within the last hundred million years have been linked to two extinction events: Chicxulub for the Cretaceous–Paleogene and the Popigai impact for the Eocene–Oligocene extinction event.
What are the 5 largest craters?
Here are five of the biggest-known impact craters caused by asteroid collisions:
- Vredefort Crater. The Vredefort crater, with an estimated diameter of 300 kilometres, is the world’s largest known impact structure.
- Chicxulub Crater.
- Sudbury Basin.
- Popigai Crater.
- Manicouagan Reservoir.
Which country has the largest crater?
In South Africa, the Vredefort Crater (opens in new tab), also known as the Vredefort Dome is the world’s largest known impact crater, according to NASA Earth Observatory.
Where is the biggest crater in America?
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 giant crater in the US?
Meteor Crater, also called Barringer Meteorite Crater, Coon Butte, Arizona Meteor Crater, or Canyon Diablo, rimmed, bowl-shaped pit produced by a large meteorite in the rolling plain of the Canyon Diablo region, 19 miles (30 km) west of Winslow, Arizona, U.S. The crater is 4,000 feet (1,200 metres) in diameter and
What is the largest object to hit Earth?
The Chicxulub Event
65 million years ago an asteroid roughly 10 to 15 kilometers (6 to 9 miles) in diameter hit Earth in what is now Mexico. The impact killed 70% of all species on Earth, including the dinosaurs.
What is the biggest asteroid that could hit Earth?
99942 Apophis is a near-Earth asteroid and potentially hazardous asteroid with a diameter of 370 metres (1,210 feet) that caused a brief period of concern in December 2004 when initial observations indicated a probability up to 2.7% that it would hit Earth on April 13, 2029.
When was the last time an asteroid hit Earth?
However, asteroids with a diameter of 20 m (66 ft), and which strike Earth approximately twice every century, produce more powerful airbursts. The 2013 Chelyabinsk meteor was estimated to be about 20 m in diameter with an airburst of around 500 kilotons, an explosion 30 times the Hiroshima bomb impact.
Will an asteroid hit Earth 2022?
It has since been confirmed that 2022 AE1 will not impact Earth and has been removed from ESA’s risk list. So, what’s the story behind the excitement, and how can we trust this seemingly ‘meandering’ impact risk?
How big was the crater that killed the dinosaurs?
Its center is offshore near the community of Chicxulub, after which it is named. It was formed slightly over 66 million years ago when a large asteroid, about ten kilometers (six miles) in diameter, struck Earth. The crater is estimated to be 180 kilometers (110 miles) in diameter and 20 kilometers (12 miles) in depth.
Where did the meteor that killed the dinosaurs hit?
Scientists already know that an asteroid—or perhaps a comet—struck Earth off Mexico’s Yucatán Peninsula. The resulting 110 miles/80 kilometers wide Chicxulub crater is thought to have caused a decades-long “impact winter” that killed the dinosaurs.
Why does Canada have so many impact craters?
About 290 million years ago, two large meteorites crashed into Earth and formed the two impact craters the make up this lake system in Quebec’s largest national park. Originally close to the equator, these craters were slowly pushed into northern Canada by millions of years of plate tectonics.
Where is Earth’s most preserved crater located?
northern Arizona desert
Located in the vast high plains of the northern Arizona desert, the Barringer Meteorite Crater is the largest meteor impact crater in the United States, and the best preserved on Earth.
What is the newest crater on Earth?
Then, in July 2021, scientists confirmed that a geological structure in the Lesser Xing’an mountain range had formed as a result of a space rock striking Earth. The team published a description of the newfound impact crater that month in the journal Meteoritics and Planetary Science (opens in new tab).
What is the only US city built within a meteor crater?
Middlesboro, KY is the only city in the US now known to be built within a meteor crater. William M. Andrews Jr., a geologist with the Kentucky Geological Survey, said erosion and vegetation have hidden most signs of the meteor’s impact.
What city was built inside a crater?
Nördlingen is literally made of diamonds—millions of microscopic diamonds to be exact—with the town itself constructed within an ancient impact crater.
Who owns the Meteor Crater in Arizona?
the Barringer family
Despite historic attempts to make the crater a public landmark, the crater remains privately owned by the Barringer family to the present day through their Barringer Crater Company, which proclaims it to be the “best-preserved meteorite crater on Earth”.
Is the Meteor Crater in Arizona worth it?
The Meteor Crater was one of those things you don’t really hear about, but it is an awesome thing to see, and definitely worthy of being considered a Route 66 Landmark. A panoramic view of the Meteor Crater in Winslow, Arizona.
What happened to the asteroid that hit Arizona?
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. (Click here to learn about the geology of the region).
