NASA's Center for Near-Earth Object Studies says that the probability of asteroid 2024 YR impacting Earth on 22 December 2032 has increased to 2.3%, or a (1-in-43) chance, following further observations of its trajectory. More observations are planned in the coming months to gather data on the asteroid before it moves too far away from Earth-based telescopes to be accurately observed.
