Near-Earth Asteroids as of September 2023

September 2023 Each month, NASA’s Planetary Defense Coordination Office releases a monthly update featuring the most recent figures on NASA’s planetary defense efforts, near-Earth object close approaches, and other timely facts about comets and asteroids that could pose an impact hazard with Earth. Here is the what we’ve found for September.
