mp|2007 CA|19 (also written 2007 CA19) is a near-Earth asteroid. It 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 CA19, 99942 Apophis was the object with the highest Palermo Scale rating.

mp|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 metres in diameter with a mass of a 1.2x10¹² kg. Until February 15, it had an impact probability of 1/625000 (computed by NASA's Sentry program). Additional observations through February 19 decreased the impact probability of ~1 in 300 million, making it of negligible concern.
