Asteroids Big Enough To Destroy Cities Hit Earth With Terrifying Frequency, Scientists Reveal

The mysterious ‘Tunguska event’ was the largest asteroid impact in recorded history and caused an explosion 1,000 times more powerful than the bomb which destroyed Hiroshima. Now scientists have calculated how often one of these terrifying space rocks hits our planet. This is a major threat to the survival of humans.

In 1908, 80 million trees were knocked down over an area of 800 square miles hidden deep in the Siberian forest when a meteor which was up to 190 metres wide crashed into Earth.

If the object which caused this devastation had hit a populated area, it could have killed millions and razed a city to the ground.

In a research paper published on Arxiv, a team of scientists said our planet is hit by slightly bigger objects every 1,000 years – although they also claimed an impact from a smaller object might happen during a period of between 100 and 500 years. ‘There remains a potentially significant discrepancy in the frequency of Tunguska-sized and Chelyabinsk-sized impact,’ they wrote, also referring to an incident in 2013 which left 400 people injured. 

Although an impact from a Tunguska-sized object would not wipe out humanity, it could kill millions. These smaller rocks are also hard to guard against because they can sneak up on our planet and may only be detected just before they hit us. The Taurid meteor shower is believed to be the source of the 500ft meteor which exploded in the sky over the Stony Tunguska river in 1908.

Last year, scientists have warned that asteroids big enough to cause ‘continental’ damage could be lurking within a new branch of the Taurids.

Researchers at the Czech Academy of Sciences writing in Astronomy and Astrophysics, warn that a previously undiscovered branch of the Taurids could harbour asteroids of up to ‘several hundred meters in diameter’. So what do you think about this?
