Giant meteor exploded in Earth's atmosphere in December


It took place on 23:50 GMT on 18 December 2018 over the Bering Sea - between Russian Federation and Alaska.

The meteor exploded near Russia's Kamchatka Peninsula over the Bering Sea on December 18 previous year.

The meteor entered the Earth's atmosphere nearly vertically at a steep angle of 7 degrees and at a speed of around 32km/s.

Military satellites detected the meteor at the time and sent the data to NASA, however the detonation had gone comparatively unrecognized by most.

It is believed to be the second largest meteor explosion in the last 30 years, and the biggest since the high-profile Chelyabinsk fireball of 2013. Back then social media was flooded with videos and photos of the fireball blazing in the sky brighter than sun. Brown. He noted that had the object's orbit intersected with Earth just four hours earlier, it would have exploded over Fort McMurray, Alta., where the force of the high-altitude blast would have been sufficient to shatter windows.

'That was 40 per cent the energy release of Chelyabinsk, but it was over the Bering Sea so it didn't have the same type of effect or show up in the news, ' the BBC reports.

The energy released during the Meteor explosion was ten times more than the atomic bomb detonated at Hiroshima in 1945. The meteor exploded at 25.6km above the Bering Sea with an energy of 173 kilotons.

Impact events are surprisingly common.

The planetary defense officer at NASA, Lindley Johnson, reported during an interview with BBC News, that such a massive meteor explosion should only take place two or three times in 100 years.

While it may appear small from satellite images, the explosion had 10 times the energy of the Hiroshima atomic bomb. "That's another thing we have in our defense, there's plenty of water on the planet". Dr. Kelly Fast, a researcher with the US space agency, explained that the area of explosion is not far from the usual route of several commercial flights between America and Asia. The US Air Force announced NASA about it, and the US space agency began the investigation of the space rock blast.

The Earth is regularly pelted by comets and asteroids but it is rare to have objects this big to approach the planet.
