Over the next several weeks, astronomers will be looking closely at an asteroid called 2024 YR4 that could be as big as a football field as they try to determine how likely it is to strike Earth in 2032.

The chances that a space rock could hit Earth in less than a decade just went up slightly, according to NASA scientists. The asteroid 2024 YR4, which is expected to pass Earth in 2032, was recently calculated to have a 1-out-of-43 chance of striking our planet. By contrast, last week 2024 YR4 had only a 1-out-of-83 chance of striking our planet.
