Asteroid 2017 EJ3 is a near-Earth object catalogued by NASA under reference ID 3771028. Its estimated diameter is 60–134 m (average 97 m), inferred from brightness rather than measured directly. Its closest catalogued approach to Mars occurs on Mon, Jan 18, 2077, missing by 13,886,245 km — 36.11 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.
