Asteroid 2017 WK15 is a near-Earth object catalogued by NASA under reference ID 3789686. Its estimated diameter is 12–27 m (average 20 m), inferred from brightness rather than measured directly. Its closest catalogued approach to Earth occurs on Mon, Nov 27, 2017, missing by 3,356,020 km — 8.73 lunar distances. NASA does not classify it as a potentially hazardous asteroid.
This score ranks how notable the asteroid approach is. It is not an impact prediction.
