According to NASA, an explosion 15 miles away from Earth contained more than ten times the energy of Hiroshima.

A huge meteor exploded in December over the Bering Sea in the largest recorded event since a 2013 incident in Russia.

According to a NASA tracker Fireballs fireballs reported by government sensors on December 18, 2018, NASA describes them as "exceptionally bright meteors that are spectacular enough to be seen over a very wide area."

The explosion generated energy equivalent to about 173 kilotons of TNT, the agency said. That's ten times more than the energy generated by the atomic bomb used in Hiroshima in 1945, according to the MIT Technology Review.

"Such an event could happen two to three times per century," says Lindley Johnson, planetary defense officer at NASA said to USA TODAY.

Johnson said this was the second biggest event they've seen in the past 30 years.

Based on the amount of energy released, the meteor is estimated to be between 10 and 14 meters in size, said Kelly Fast, program manager for Objects near Earth at NASA.

The last meteor of this magnitude continued to explode Earth was in 2013, when a 20-meter meteor exploded in the Chelyabinsk region of Russia and was captured on video by security and dashboard cameras. Johnson said the meteor generated 440 kilotons of TNT.

At the time of the 2013 Meteor, NASA said it was the largest in more than 100 years and was exploding with the power of 20 nuclear bombs.

Johnson said NASA has reached an agreement with the US Air Force to exchange data when natural events such as the Meteor Explosion take place, sometimes taking days or weeks to complete.

Almost said more information about the meteor in December did not come out now because the location of the explosion was in a remote location in the middle of the ocean. "In the case of 2013, it happened over a populated area, many people could see it," she said.
