Asteroid impacts have shaped Earth’s history, causing significant changes and destruction. In the last 20,000 years, several massive asteroid hits have been recorded. The Kaalijarv Craters in Estonia, dating back to 1530 BC, resulted from an asteroid impact that created nine craters, with the largest being 110 meters in diameter. Another significant event is the Campo del Cielo in Argentina, around 2000 BC, where a 15-meter diameter asteroid created a field of craters, causing widespread destruction over 60 km².

One of the most well-known impacts is the Tunguska Event in 1908, which flattened over 80 million trees across 2,150 km² in Siberia, Russia. The Chelyabinsk Meteor in 2013 is a recent event where a 20-meter asteroid exploded in the atmosphere, causing injuries to over 1,500 people and damaging numerous buildings in Chelyabinsk Oblast, Russia.

These events highlight the potential devastation caused by asteroid impacts.
