Since the start of the 21st century, dozens of incoming asteroids have slammed into Earth, some of them packing far more energy than a city-destroying atomic bomb. A list of the impacts shown in the video above can be found here.

Between 2000 and 2013, a network of sensors that monitors Earth around the clock listening for the infrasound signature of nuclear detonations detected 26 explosions on Earth ranging in energy from 1-600 kilotons – all caused not by nuclear explosions, but rather by asteroid impacts.
To put this data in perspective, the atomic bomb that destroyed Hiroshima in 1945 exploded with an energy impact of 15 kilotons.

These findings were recently released from the Nuclear Test Ban Treaty Organization, which operates the network.

While most of these asteroids exploded too high in the atmosphere to do serious damage on the ground, the evidence is important in estimating the frequency of a potential “city-killer-size” asteroid. On February 15, 2013 in Chelyabinsk, Russia, a 600-kiloton meteor impact damaged hundreds of buildings and injured more than 1,000 people.

The B612 Foundation — an asteroid-hunting non-profit organization founded by former NASA astronauts — hopes to raise awareness about why Earth needs asteroid-detection systems. The Foundation aims to build a privately funded infrared space telescope to find dangerous asteroids when they are still millions of miles away.
