The recently discovered asteroid 2024 YR4 is on a collision path with Earth, and its risk level has been raised to 1-in-43 by scientists. With a size between 130 to 300 ft, it could impact on December 22, 2032. Experts indicate that even a successful deflection mission like NASA's DART, which redirected the asteroid Dimorphos, may not be enough. Limited time and the complexities of deflection missions highlight an urgent need for preparedness to possibly avert this threat.
We might not be able to stop 2024 YR4 from hitting Earth, even with a deflection mission, with only less than eight years to address it.
The DART mission successfully altered Dimorphos' orbit, providing a proof-of-concept for asteroid deflection, but 2024 YR4's imminent threat requires urgent action.
