The December 18 fireball created the biggest airburst since the Chelyabinsk meteor of 2013.
A meteor that exploded over the Bering Sea in December released 10 times the energy of an atomic bomb into the atmosphere.
The asteroid, which was about 10 meters wide, disintegrated in the skies off the coast of Russia’s Kamchatka peninsula on December 18. It unleashed 173 kilotons of energy, making it the second-biggest fireball in recent decades next to the 440-kiloton meteor that rocked the Russian city of Chelyabinsk on February 15, 2013.
Unlike the Chelyabinsk event, the Bering Sea fireball did not make a big news splash immediately after it impacted in part because it occurred over a remote and unpopulated area. Chelyabinsk, in contrast, is home to more than one million people, many of whom witnessed or were injured by the explosion. Some even captured the dazzling airburst on camera, which instantly enabled viewers around the world to share the sight of the blast.
