Not flagged as hazardousNASA/JPL page

Notable Pass

Asteroid 2010 SJ is a near-Earth object catalogued by NASA under reference ID 3546741. Its estimated diameter is 46–103 m (average 75 m), inferred from brightness rather than measured directly. Its closest catalogued approach to Earth occurs on Fri, Oct 1, 2010, missing by 7,415,847 km — 19.28 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.
