NASA says the bus sized meteor that flew over Russia may be the largest to come in contact with the Earth in more than 100 years.
NASA estimates the meteor weighed about 7,000 pounds and exploded with the force of 20 atomic bombs.
It came into the atmosphere at 33,000 miles per hour and shattered into pieces somewhere between 18-32 miles above the ground.
Luckily the atmosphere absorbed a majority of that energy.
About 1,100 people were injured by shattered glass and debris.
Don Garland, Director of the Noble Planetarium at the Fort Worth Museum of Science and History explains the phenomenon.
