Dating back 1.8 billion years, it is also one of the oldest known impact structures in the world.
Located in what is now Lake Acraman
This crater is not exposed at the surface and has led to many discrepancies regarding its actual size.
This impact crater formed what is now Lake Manicouagan. Even with erosion, it's considered one of the largest and best-preserved craters on Earth
Located near the Kalahari Desert in South Africa, this crater contained the fossilized remains of the meteorite that created it.
Some have claimed that the impact structure actually consists of two adjacent craters: the Kara and the Ust-Kara crater.
Many scientists believe that the meteorite that left this crater caused or contributed to the extinction of the dinosaurs.
Russian scientists claim that this crater site contains trillions of carats of diamonds, making it one of the largest diamond deposits in the world.
Discovered in the early 1980s, the Chesapeake Bay Crater is located approximately 125 miles (201 kilometers) from Washington, D.C.
