Asteroid 2008 TX3 Close Approach

Not flagged as hazardousNASA/JPL page

Notable Pass

Asteroid 2008 TX3 is a near-Earth object catalogued by NASA under reference ID 3430304. Its estimated diameter is 28–62 m (average 45 m), inferred from brightness rather than measured directly. Its closest catalogued approach to Earth occurs on Sat, Nov 1, 2008, missing by 3,462,610 km — 9.00 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.
