(CBC) The largest fireball to streak through the Earth's atmosphere since the Chelyabinsk meteor in 2013 was detected over the Southern Atlantic Ocean on Feb. 6, NASA reports.
The recent meteor was detected about 31 kilometres over the South Atlantic, more than 1,000 kilometres off the coast of southern Brazil, NASA reported on its Fireball and Bolide Reports website.
It was travelling at more than 14 kilometres per second, and its energy on impact was equivalent to about 13,000 tonnes of TNT, NASA said. That's slightly less energy than the atomic bomb dropped on Hiroshima during the Second World War. The Hiroshima device exploded with an energy equivalent to 15,000 tonnes of TNT.
