However, Asteroid 2024 YR4 has a 2.3 percent chance of colliding with Earth in seven years' time, and its estimated width of 90m means it is roughly the size of Big Ben. The celestial body has been closely monitored by NASA since its December 2024 discovery.

YR4 has a 2.2% chance of striking Earth in seven years, but recent updates keep pushing the odds in the wrong direction.

YR4 has just above a 1% chance of crashing into Earth in 2032, which is why astronomers and space agencies are paying attention to it.

A newly discovered asteroid named 2024 YR4 now has a 2.2% chance of affecting Earth in 2032 after recent observations.

By comparison, the asteroid that wiped out the dinosaurs and 70% of all other animal species on Earth around 65 million years ago was roughly 6 to 9 miles wide. Other notable impact events include one in 1908,

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.
