Chelyabinsk meteor

The Chelyabinsk meteor was a small asteroid that entered Earth's atmosphere over Russia on February 15, 2013. It exploded in a bright fireball about 30 kilometers above ground, creating a powerful shockwave that shattered windows and damaged buildings, injuring over 1,600 people. The meteor weighed about 13,000 metric tons and was about 20 meters wide before it disintegrated. This event highlighted the potential hazards of near-Earth objects and spurred discussions about planetary defense strategies to track and mitigate threats from space.
