363790 passes about 20× the distance to the Moon from Earth (7,703,376 km). It is 510–1600 m across (estimated). 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.
