99942 Apophis (provisional designation 2004 MN 4) is a near-Earth asteroid and a potentially hazardous object with a diameter of 370 metres (1,210 feet) [3] 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 on April 13, 2029.
