The asteroid was discovered on 20 September 2006, by astronomers of the Catalina Sky Survey, using a dedicated 0.68-meter telescope at Mount Lemmon Observatory in Arizona, United States.

Description
Originally listed with a Torino Scale hazard rating of 0, this was raised to a rating of 1 on 22 December 2006 as a result of additional observations and refinement of the orbital calculations. However, on 9 January 2007 it was returned to a rating of 0. It was removed from the Sentry Risk Table on 7 February 2007.
