**** is a sub-kilometer asteroid, classified as a near-Earth object and potentially hazardous asteroid of the Apollo group. It briefly led the impact hazard list with a Torino Scale impact risk value of 1 for one week, ending on February 19, 2007. Before and after , 99942 Apophis was the object with the highest Palermo Scale rating. With an observation arc of 4.8 days, it had a Palermo Scale of −0.88.

was discovered on February 11, 2007, by the Catalina Sky Survey at the University of University of Arizona. The object is estimated at 966 meters in diameter with a mass of a 1.2 trillion kg. Until February 15, it had an impact probability of 1/625,000 for the day March 14, 2012. Additional observations through February 19 decreased the impact probability to ~1 in 300 million, making it of negligible concern. It was removed from the Sentry Risk Table on February 22, 2007.

passed about 0.007 AU from Venus on July 6, 1946.
