According to NASA, an explosion of 15 miles of earth contains more than 10 times more energy than Hiroshima.
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.
