How NASA science data defends Earth from asteroids

The asteroid 2024 YR4 made headlines in February with the news that it had a chance of hitting Earth on Dec. 22, 2032, as determined by an analysis from NASA’s Center for Near Earth Object Studies (CNEOS) at the agency’s Jet Propulsion Laboratory in Southern California. The probability of collision peaked at over 3% on Feb. 18—the highest ever recorded for an object of its size. This sparked concerns about the damage the asteroid might do should it hit Earth.
