#Asteroid Terrestrial-impact Last Alert System
Maunakea and Haleakalā telescopes eye asteroid trajectory
NASA’s Center for Near Earth Object Studies estimates a 1% chance that asteroid 2024 YR4 could collide with Earth in 2032, based on current observations. Throughout the coming months, astronomers will closely monitor the 180-foot (55-meter)-wide object to refine its orbit and improve predictions of its future trajectory. No asteroid of this size has ever reached a 1% impact probability in the past two decades of near-Earth object tracking, making 2024 YR4 a rare and closely watched case.
