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 2007 CA 19, 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. 2007 CA 19 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. 2007 CA 19 passed about 0.007 AU km mi on on from Venus on July 6, 1946.
