2026 OD3 passes inside the Moon's orbit, about 226,796 km from Earth's centre (0.6× the distance to the Moon). It is 6–17 m across (estimated). If a rock this size hit Earth, it would burn up as a bright fireball high in the atmosphere; at most, small meteorites reach the ground. Astronomers spot one this size passing inside the Moon's orbit about 100 times a year, and many more pass unseen. This is a routine close approach with no known impact risk.
