That means a round space rock 66 feet wide (20 m) would have a mass of 6459 tons (5,860 metric tonnes) if it were a carbonaceous asteroid, 12,458 tons (11,302 metric tonnes) if it were a stony
It is the Earth's sixth-largest confirmed impact structure according to rim-to-rim diameter. Mount Babel is interpreted as the central peak of the crater, formed by post-impact uplift. 1992 radiometric dating has estimated that impact melt within the impact structure has an age of 214 ± 1 million years.
The Vredefort crater in South Africa: Created about 2 billion years ago, this 160 Kms large crater is remnant of the largest asteroid to hit Earth. Based on the crater size, it is estimated that the asteroid must have been 10-15Kms in diameter. For reference, it is bigger than the one that killed dinosaurs.
The crater was discovered in the heavily forested Lesser Xing’an mountain range, where local residents knew it as “Quanshan,” or “circular mountain ridge.” The Yilan crater, slightly larger than Xiuyan, spans about 1.85 kilometers (1.15 miles), making it the largest crater on Earth under 100,000 years old.
The 60-tonne, 2.7 m-long (8.9 ft) long Hoba meteorite in Namibia is the largest known intact meteorite. A meteorite is a solid piece of debris from an object, such as a comet, asteroid, or meteoroid, that originates in outer space and survives its passage through the atmosphere to reach the surface of a planet or moon.
Here’s my list of Earth’s Ten Most Impressive Impact Craters, starting with #1. the largest and oldest known impact crater, Vredefort Crater, shown above, located in South Africa. It is
