"Experts at NASA’s Center for Near Earth Object Studies at the agency’s Jet Propulsion Laboratory have updated 2024 YR4’s chance of impacting the Moon on December 22, 2032 from 1.7 as of late February to 3.8 percent," the agency said this week.

The city-killer asteroid's Moon impact risk has almost more than doubled, according to new NASA reports. Here's what we know.

A large asteroid whose chances of hitting Earth have been all but ruled out is now slightly more likely to hit the Moon than previously thought, Nasa says. When first discovered, asteroid 2024 YR4 had a very small chance of impacting Earth in 2032 but the US space agency has cut that chance to 0.004%.
