YR4 has a roughly 2 percent chance of hitting Earth in 2032, and “is large enough to cause localized damage,” NASA says.

Scientists recently doubled the chances that Asteroid 2024 YR4 will hit Earth in 2032. While earlier estimates said the chance of the giant space rock- roughly the size of Big Ben- had around a one per cent chance of collision with our planet, this has now risen to 2.3 per cent, or around one in 43.
