99942 passes inside geosynchronous orbit, about 38,005 km from Earth's centre (0.10× the distance to the Moon). It is about 340 m across (measured). If a rock this size hit Earth, the result would be devastation on a national to continental scale, with global climate effects possible depending on the impact site. This is a routine close approach with no known impact risk.
