An asteroid that's big enough to wipe out a city has a 1-in-43 chance of hitting our planet in the year 2032. But according to new calculations, there's an even smaller chance that it might crash into the moon instead.

The ‘city killer’ asteroid (possibly) heading our way might spare us and slam into the Moon instead, scientists said. The space rock known as 2024 YR4 has a 2.1% chance of hitting Earth based on current observations.

The threat of a newly discovered asteroid has risen slightly in the past few weeks, as the world’s telescopes rush to track its course. New calculations suggest there's a 2% chance the space rock 2024 YR4 will smack Earth in 2032.
