Asteroid 2010 TW54 Close Approach

Not flagged as hazardousNASA/JPL page

Close Watch

Asteroid 2010 TW54 is a near-Earth object catalogued by NASA under reference ID 3548666. Its estimated diameter is 8–18 m (average 13 m), inferred from brightness rather than measured directly. Its closest catalogued approach to Earth occurs on Sat, Oct 9, 2010, missing by 161,144 km — 0.42 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.
