A massive asteroid that is twice as big as Big Ben could plunge into Earth in just five years, NASA warned.
The asteroid, called 2018 LF16, is expected to affect our planet on August 8, 2023.
Fortunately, the probability of this is very low, with NASA predicting a 99.99999967 percent chance of a miss.
Asteroid 2018 LF16 is about 213 meters wide – about twice the size of the Big Ben clock tower in London, or the size of the Golden Gate Bridge in San Francisco.
Although the probability that the asteroid crashes on the earth is low, this can lead to widespread destruction.
Such an object would have an impact force of 50 Megatons – the equivalent of the Tsar Bomba nuclear device.
The European Space Agency stated: "Some asteroids are very large and would cause massive destruction if they hit Earth, but their estimated population in our solar system is quite small and more than 90 percent of them are detected. impact.
"Some are very small – smaller than 10 m in diameter – and only a small fraction of the estimated population has been detected, but any effect would be harmless.
"The biggest challenge comes from the population of medium-sized objects, varying from dozens to hundreds of meters in diameter."
