What changed in the risk assessment for Asteroid 2024 YR4?
Asteroid 2024 YR4 was initially assessed to have a 3.1% chance of hitting Earth in 2032. However, recent observations have ruled out this risk, indicating that it now poses virtually no threat to our planet. Instead, the likelihood of the asteroid impacting the moon has increased to 3.8%, prompting further monitoring.
