FRONTroomsized meteor came out of nowhere and exploded with force of Hiroshima bomb


NASA has revealed the sudden arrival of the seven-metre space rock earlier this month.

The bright meteor, about the size of an average family home living room, exploded in the air 620 miles from the Brazillian coast.

The energy released was equivalent to 13,000 tons of TNT – the same as the first atomic bomb blast in Hiroshima, according to the US space agency.

n February 2013, a 19-metre meteor came from nowhere to explode in the sky above Chelyabinsk in Russia with the force of 500,000 tonnes of TNT.

The energy released shattered glass on hundreds of buildings and more than 1,000 people were injured.

The new meteor is believed to be the biggest to make it to Earth since Chelyabinsk, but it had no impact as it was so far out to sea and not big enough to trigger tsunamis, despite entering our atmosphere at 41,600mph.

It was only picked up by NASA as it entered the atmosphere.

Phil Plait, who writes the Bad Astronomy blog for, moved to ally fears over more frequent meteor strikes.

He said: “Had it happened over a populated area it, would’ve rattled some windows and probably terrified a lot of people, but I don’t think it would’ve done any real damage.

“Impacts like this happen several times per year on average, with most going unseen.”

If an asteroid of several hundred meters made it through our atmosphere, it could destroy a city or worse.

A 30-metre-wide rock may pass close to Earth next month, but NASA experts have said there is no reason to worry as it will not hit and there are no significant impacts expected on Earth for the next century at least.
