mp|2006 XG|1 (also written 2006 XG1) is a near-Earth asteroid with a low but non-zero probability of impacting Earth on October 31, 2041. Originally listed with a Torino Scale hazard rating of 0, this was raised to a rating of 1 on December 22, 2006 as a result of additional observations and refinement of the orbital calculations. However, on January 9, 2007 it was returned to a rating of 0.

mp|2006 XG|1 was discovered on September 20, 2006 by the University of Arizona's Catalina Sky Survey. The object is estimated to be between 600 and 1400 meters by NEODyS, and approximately 670 meters by the JPL Sentry System. The estimated mass is 4.2×10¹¹ kg.
