NASA Raises Chance for Asteroid to Hit the Moon
MOON, JUN 16 – Asteroid 2024 YR4 has a 4.3% chance to hit the Moon in 2032, potentially creating a 1 km crater and ejecting debris that could increase satellite collision risks by years in days.
- Astronomers identified the space object 2024 YR4 at the end of December 2024 and concluded it does not threaten Earth, although it could potentially collide with the Moon in 2032.
- Initial concern arose from early predictions showing a 3.8 percent chance of lunar impact, which recent observations using JWST raised to 4.3 percent.
- Scientists refined 2024 YR4's orbit by 20 percent, estimating the asteroid will create a roughly 1 km crater on the Moon if it hits on December 22, 2032.
- Researchers caution that debris ranging from 0.1 to 10 mm produced by the impact could pose a long-term hazard to satellites orbiting close to Earth, although the event would have no significant effect on the Moon’s trajectory.
- The asteroid will pass close to Earth in 2028, allowing further observation to update lunar impact probabilities and improve planetary defense measures.

Asteroid on collision course with moon could fire shrapnel at Earth
Earth is no longer at risk of a direct collision with the asteroid 2024 YR4, but an impact on the moon in 2032 could send debris hurtling towards our planet that could take out orbiting satellites
The mother of all meteor showers could threaten satellites
Shortly after astronomers detected asteroid 2024 YR4 on December 27, 2024, they realized it posed no threat to Earth. But it could still impact the moon in 2032. The impact debris could threaten satellites and trigger an extraordinarily stunning meteor shower.
