Of those that have made terrestrial landings, most have touched down in North America (32%), followed by Europe (22%) and Russia and Asia (16%), according to the Earth Impact Database (opens in new tab). Of the known impact craters (opens in new tab), 44 measure 12 miles (20 kilometers) across or larger.

What country has the most craters?
Number of Impact Craters by Country
| Location | Count |
|---|---|
| Canada | 32 |
| USA | 28 |
| Australia | 26 |
| Russia | 19 |
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.
Where are craters most likely to occur?
Meteorite craters are more common on the Moon and Mars and on other planets and natural satellites than on Earth, because most meteorites either burn up in Earth’s atmosphere before reaching its surface or erosion soon obscures the impact site.
Where are craters on Earth located?
10 Ma or more
| Name | Location | Country |
|---|---|---|
| Vredefort | Free State | South Africa |
| Chicxulub | Yucatán | Mexico |
| Sudbury | Ontario | Canada |
| Popigai | Siberia | Russia |
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.
Why are there so many craters in North America?
This list includes all 60 confirmed impact craters in North America in the Earth Impact Database (EID). These features were caused by the collision of large meteorites or comets with the Earth.
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.
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 deepest crater on Earth?
The Vredefort impact structure /ˈfrɪədəfɔːrt/ is the largest verified impact structure on Earth. The crater, which has since been eroded away, was around 160–300 km (100–200 mi) across when it was formed.
Where is the biggest crater in the universe?
List of largest craters in the Solar System
| Body | Crater | Crater diameter |
|---|---|---|
| Earth | Chicxulub crater | 182 km (113 mi) |
| Moon (moon of Earth) | Procellarum | 3,000 km (2,000 mi) |
| South Pole–Aitken basin | 2,500 km (1,600 mi) | |
| Imbrium | 1,145 km (711 mi) |
Why are craters rare on Earth?
The reason that earth exhibits so few craters compared with other planets of comparable size is that the surface is constantly being reworked. This occurs through both the processes of weathering and mountain-building crustal deformation.
Why is it so difficult to find craters on Earth?
So why are there so few craters on Earth? NASA notes that Earth is equipped with three processes that eat up craters relatively quickly: erosion, tectonics, and volcanism. These forces leave only the largest scars from meteorites or asteroids — unlike, say, the moon, which can’t gobble up craters.
How many crater does Earth have?
But the surface of Earth, constantly eroded by wind and rain, hides its history. Just 128 confirmed impact craters have been spotted on Earth’s surface.
Which planet is full of craters?
Mercury and the Moon
Impact craters dominate the surfaces of Mercury and the Earth’s Moon. Both bodies lack liquid water on their surfaces that would erode impact craters over time. They also lack an atmosphere which, on planets like the Earth and Venus, could disintegrate meteoroids before they impact the surface.
How many crater are there on Earth?
Still, almost 170 terrestrial impact craters have been identified on our planet. These range in diameter from a few tens of meters up to about 300 km (186 miles), and they range in age from recent times to more than two billion years.
Where is the largest impact crater in the US?
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.
What is the newest impact crater on Earth?
The Nadir Crater
The Nadir Crater, located 300 meters below the seabed, was discovered accidentally by Dr. Uisdean Nicholson, a geoscientist at the Herriot-Watt University, while he was analyzing seismic survey data to better understand past climatic changes.
Was crater lake caused by a meteor?
3. Crater Lake was formed by the fall of a volcano. Mount Mazama, a 12,000-foot-tall volcano, erupted and collapsed approximately 7,700 years ago, forming Crater Lake. Mount Mazama was an important symbol to the native Makalak people who lived in the surrounding areas.
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.
Has a meteor ever hit the USA?
Falls. There have been 156 observed and recovered meteorite falls in the U.S. The first was Weston (Connecticut) in 1807 and the last (as of August, 2021) was Hamburg (Michigan) in 2018. On average, that is 1.4 meteorite falls per year.
