The most significant fireball event in over 100 years occurred over Russia in 2013. We actually got hit by an asteroid that was the size of a small building and that one disintegrated about 20 kilometers above the city of Chelyabinsk. And it deposited a fair number of meteorites in. the ground and I happen to have a piece of the Chelyabinsk

An asteroid big enough to wipe out a city will zip harmlessly between Earth and the moon's orbit this weekend, missing both celestial bodies. Saturday’s close encounter will offer astronomers the chance to study a space rock from just over 100,000 miles (168,000 kilometers) away. While asteroid flybys are common, NASA said it’s rare for one so big to come so close — about once a decade.

As many as 800 asteroids are hovering around Earth, posing many a risk. Some are particularly dangerous like the Apophis asteroid — God of Chaos — that is supposed whiz past earth in 2029 Anonymous, Calumet City, Illinois. Yeomans: Fairly conclusive evidence exists of a major asteroid impact some 65 million years ago, about the time the dinosaurs became extinct. Scientists

The Chicxulub impact occurred 66 million years ago when an asteroid approximately 12 kilometers (7 miles) wide slammed into Earth. The collision took place near what is now the Yucatán peninsula CNN —. A newly discovered asteroid roughly the size of an Olympic swimming pool has a “small chance” of colliding with Earth in 23 years, with a potential impact on Valentine’s Day in 2046
The study also finds that these mass extinctions align with major asteroid impacts and devastating volcanic eruptions. Paleontologists recognize five big mass extinction events in the fossil record .
Bennu is classified as a “potentially hazardous asteroid,” meaning the object is more than 460 feet (140 meters) wide and could theoretically come within 4.65 million miles of Earth. A 2014

Apophis is an asteroid that became notorious in 2004 as a potential threat to Earth. Also known as asteroid 99942, the near-Earth object is estimated to be about 1,100 feet (340 meters) across and
