2024 QP2 passes inside the Moon's orbit, about 220,494 km from Earth's centre (0.6× the distance to the Moon). It is 93–300 m across (estimated). If a rock this size hit Earth, the result would be destruction across a metropolitan region, with a crater kilometers wide — or a major tsunami from an ocean impact. Known asteroids this size pass inside the Moon's orbit about once every 20 years. This is a routine close approach with no known impact risk.
