How scientists could stop the ‘city-killer’ asteroid from striking Earth in 2032
The asteroid, named Asteroid 2024 YR4, has a 1.3 per cent – or one in 83 – chance of striking Earth on December 22 in 2032. Scientists estimate the lump of rock measures somewhere between 40 metres (131 feet) and 100 metres (328 feet) wide, which is around the length of a Boeing 747 or the height of Big Ben.
