Meteor explodes over US with blast equivalent to 300 tonnes of TNT

emirates7 - A meteor crashing toward Earth exploded over the northeastern United States on Saturday, NASA said, setting off booms that echoed over the region with a blast equivalent to 300 tonnes of TNT.

The fireball broke up over northeastern Massachusetts and southeastern New Hampshire at 2:06 pm (1806 GMT), NASA's Deputy News Chief Jennifer Dooren said in a statement.

"This fireball was not associated with any currently active meteor shower, but it was a natural object and not a re-entry of space debris or a satellite," she said.

The meteor was travelling at 75,000 mph (more than 120,000 kph) at an altitude of 40 miles when it broke apart, Dooren said.
