This animation shows the distance between the Apophis asteroid and Earth at the time of the asteroid's closest approach. The blue dots are the many man-made satellites that orbit our planet, and the pink represents the International Space Station.
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, April 13, 2029.
"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 ...
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.
English: The close approach of 99942 Apophis (previously better known by its provisional designation 2004 MN 4) to the Earth and Moon on Friday, April 13, 2029 The small white bar indicates uncertainty in the range of possible positions.
After delivering an asteroid sample to Earth Sunday, the newly expanded OSIRIS-APEX mission is heading to Apophis. The asteroid will come within 20,000 miles of Earth in 2029.
While the size of a very small fraction of these asteroids is known to better than 1%, from radar observations, from images of the asteroid surface, or from stellar occultations, the diameter of the vast majority of near-Earth asteroids has only been estimated on the basis of their brightness and a representative asteroid surface reflectivity ...
It gained some public interest when it became clear, in January 2005, that the asteroid 99942 Apophis would miss the Earth in 2029 but may go through one or another keyhole leading to impacts in 2036 or 2037. Further research has since been done, however, which revealed the probability of Apophis passing through the keyhole was extremely low. [1]
