Chelyabinsk Meteor

About

The Chelyabinsk meteor was a significant asteroid event that occurred on February 15, 2013, over Chelyabinsk, Russia. The asteroid, approximately 20 meters in diameter, entered Earth's atmosphere at a speed of about 68,000 km/h. It exploded at an altitude of around 30 km, releasing energy equivalent to about 440,000 tons of TNT. This explosion generated a powerful shock wave that shattered windows and damaged buildings across six cities, injuring over 1,500 people. The Chelyabinsk meteor highlighted the importance of asteroid detection and planetary defense. It was extensively documented by dashboard cameras and witnesses, providing valuable data for scientists. A large fragment of the meteorite was recovered from Lake Chebarkul, weighing about 654 kg. The event led to increased global efforts in asteroid tracking and mitigation strategies, including the establishment of NASA's Planetary Defense Coordination Office. It remains one of the most significant asteroid airbursts in recent history, emphasizing the need for continued vigilance and preparedness against such events.
