Not flagged as hazardousNASA/JPL page

Close Watch

Asteroid 2007 UW1 is a near-Earth object catalogued by NASA under reference ID 3389195. Its estimated diameter is 77–171 m (average 124 m), inferred from brightness rather than measured directly. Its closest catalogued approach to Earth occurs on Wed, Oct 19, 2129, missing by 83,983 km — 0.22 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.
