2024 YR4 may not make catastrophic history, but it did set a new record for the JWST as the smallest object ever targeted by the telescope. It’s also one of the smallest space objects to have its size directly measured.

A huge asteroid that was briefly feared to strike Earth now has a nearly 4% chance of smashing into the moon, according to new data from the James Webb Space Telescope.

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.
