Late last year, a meteor exploded in the skies above Russia with a force 10 times that of the Hiroshima atomic bomb. But despite the meteor’s power, it somehow went unnoticed until recently.
Western University’s Peter Brown says he was reviewing data from the nuclear comprehensive test ban organization which logs large seismic events around the world.“I immediately thought this must be a fireball,” Brown told CTV London. “Probably a pretty big one."
The meteor was estimated to be between 10 and 14 metres in diameter, and have an impact energy of 173 kilotons, making it the second-most powerful of its kind in 30 years, with only the meteor that hit Chelyabinsk, Russia, in 2013 ahead of it. “This one is, certainly, a little bit different from the others,” Wiegart said. “So it's quite intriguing."
