The meteor traveled with a speed of around 19 kilometres per second (69,000 km/h or 42,900 mph). Shortly after hitting the atmosphere, it quickly became a bright streak of light across the sky in Chelyabinsk, Russia. For a few moments, the light from the meteor was greatly brighter than the Sun, even at distances of up to 100 kilometers away. It was observed and caught on cameras by a lot of people in the region and in neighboring republics. Some eyewitnesses also reported feeling intense heat from this magnificent fireball.
The meteor carried a kinetic energy equivalent to 500 kilotons of TNT, it is equivalent to 20–30 times more energy than what was released from the atomic bomb detonated at Hiroshima, Japan.
The resulting blast and shock wave shattered windows, damaged more than 7,200 buildings in six cities, and injured more than 1,000 people. The Chelyabinsk meteor is the only meteor documented and confirmed to have caused a large number of injuries.
Around eight months after the Chelyabinsk incident, a 570 kg meteorite was pulled out of Lake Chebarkul, making it one of the biggest meteorites ever recovered. Watch the meteor in the video below:
