https://www.technologyreview.com/2025/07/08/1119757/asteroid-hunt-2024-yr4-earth-planet-protection/

Latest calculations conclude no danger to Earth, but that there's a 4.3% chance 2024 YR4 will impact the lunar surface in 2032. The orbit can no longer be refined until the asteroid’s next Earth flyby in 2028.
