The enormous meteor erupted over the Bering Sea in December at the largest recorded event of the 2013 incident in Russia. fire balls. Fireballs are described by NASA as "extremely bright meteors that are impressive enough to be seen in a very broad field."

The blast generates energy roughly equivalent to 173 kilotons of TNT, the agency said. According to MIT Technology Review, this is about 10 times more than the energy generated by the nuclear bomb used in Hiroshima in 1945. "An event like this can happen two to three times a century," said Lindley Johnson.

Johnson said this was the second largest event they've seen in the last 30 years.

According to the amount of released energy, the meteor has a size between 10 and 14 meters, says Kelly Burst, head of the Earth Observation Program NASA.

The last meteor of this magnitude will explode on Earth was in 2013, when a 20-meter meteor erupted in the Chelyabinsk region of Russia, shot on video by security cameras and backgammon. Johnson said the meteor generated an energy of 440 kilotonnes from TNT.

During the 2013 meteor, NASA said it was the largest for more than 100 years, exploding with a force of 20 atomic bombs. NASA has an agreement with the US Air Force to share data when natural phenomena occur such as the blast of meteors, which can sometimes take a day or weeks to process. Now that the location of the explosion was in a remote location in the middle of the ocean. "In the case of 2013, this happened in a populated area, many people could see it," she said.
