New observations from the James Webb Space Telescope have now ruled out any chance of a lunar impact on December 22, 2032. Scientists say the asteroid is now expected to miss the Moon by about 21,200 kilometers, ending earlier concerns that gave it a small 4.3% chance of striking our natural satellite.
The updated orbit comes from Webb observations taken on February 18 and 26, 2026, which tracked the extremely faint asteroid with far greater precision than before. Researchers also got matching results from archival images that traced the object back to 2016, giving astronomers two independent lines of evidence that the Moon is safe.
While a Moon strike would not have threatened Earth directly, the case became an important real-world test of planetary defense techniques. It also highlighted how professional observatories and skilled amateur researchers can work together to refine the paths of potentially hazardous space rocks.
But there is also a little talked about dark-side to such a collision with the moon too. A major impact on the Moon wouldn’t just be a spectacular sky event, it could also create a huge and dangerous debris problem. Any satellites, spacecraft, or future infrastructure we have in the Earth-Moon environment could be at risk from an expanding cloud of fast-moving debris, and the domino effect of collisions could make the situation even worse.
Our near-space environment could end up polluted and dangerous to cross for a long time afterward. And hopefully, with what we’ve learned from NASA’s successful asteroid redirection mission, we may one day be able to apply that same kind of planetary defense know-how to nudge an incoming object off course before it ever hits the Moon and creates that kind of mess.
If a large asteroid ever did hit the Moon, would you want to watch it happen live?
