99942 Apophis is a near-Earth asteroid with a diameter of 370 meters that caused a brief period of concern in December 2004 when initial observations indicated a probability up to 2.7% that it would hit Earth or the Moon on April 13, 2029.
Additional observations provided improved predictions that eliminated the possibility of an impact on Earth or the Moon in 2029.
On April 13, 2029, Apophis will pass Earth closer than geosynchronous communication satellites but will come no closer than 31,200 kilometers (19,400 mi) above Earth's surface.
