Understanding Asteroid 2024 YR4
Asteroid 2024 YR4 poses a 1% chance of colliding with Earth, which is considerably higher than the typical 0% chance associated with most asteroids. Even though this asteroid's potential impact date is set for December 22, 2032, experts emphasize that there is no need for panic. Ongoing tracking and observation will help refine its trajectory and increase understanding of its path. This asteroid is roughly 40 to 100 meters in diameter and, while not capable of resulting in a mass extinction event, could still cause significant local damage if it were to collide with Earth.
