99942 Apophis (provisional designation 2004 MN 4) is a near-Earth asteroid and a potentially hazardous object, 450 metres (1,480 ft) by 170 metres (560 ft) in size, [3] that caused a brief period of concern in December 2004 when initial observations indicated a probability of 2.7% that it would hit Earth on Friday, 13 April 2029.

A menacing asteroid named Apophis is projected to have a close encounter with Earth in 2029, but scientists have long ruled it out as an impact risk. Asteroids safely fly by Earth all the time ...
"The deflection of Apophis by a small asteroid onto a collision course with Earth in 2029 – in addition to being extremely unlikely – will most likely be quickly eliminated as a possibility by ...
“Close,” in the space world, is a relative term. At its nearest, Apophis will pass roughly 19,000 miles (31,000 kilometers) above Earth’s surface. That's about one-10th the distance to the moon.
Asteroid impact prediction is the prediction of the dates and times of asteroids impacting Earth, along with the locations and severities of the impacts. The process of impact prediction follows three major steps: Discovery of an asteroid and initial assessment of its orbit which is generally based on a short observation arc of less than 2 weeks.
Asteroid 2003 BMY, around 120-foot, will also pass by Earth on Thursday at a distance of more than 2 million miles. Finally, asteroid 2024 BP1 , measuring in at around 130 feet, will also pass by ...
