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. But the chance of an impact is still quite slim. New calculations suggest there's a 2% chance the space rock 2024 YR4 will smack Earth in 2032.

Astronomers have upped the odds of an asteroid called 2024 YR4 striking Earth, albeit in 2032, but warn that it will most likely soon be downgraded and miss Earth.
