This animation shows the orbital trajectory of asteroid 99942 Apophis as it zooms safely past Earth on April 13, 2029. Earth’s gravity will slightly change the trajectory of Apophis as it comes within 20,000 miles (32,000 kilometers) of our planet’s surface.
99942 Apophis (provisional designation 2004 MN4) is a near-Earth asteroid and a potentially hazardous object, 450 by 170 metres in size, [3] that caused a brief period of concern in December 2004 when initial observations indicated a probability 2.7% that it would hit Earth on Friday, 13 April, 2029.
10 Μαΐ 2024 · In just under half a decade, a 1,000-foot-wide (305-meter-wide) asteroid named after the Egyptian god of chaos and destruction, Apophis, will pass within 30,000 miles (48,300 kilometers) of...
26 Μαρ 2021 · After its discovery in 2004, asteroid 99942 Apophis had been identified as one of the most hazardous asteroids that could impact Earth. But that impact assessment changed as astronomers tracked Apophis and its orbit became better determined.
7 Οκτ 2009 · PASADENA, Calif. -- Using updated information, NASA scientists have recalculated the path of a large asteroid. The refined path indicates a significantly reduced likelihood of a hazardous encounter with Earth in 2036. The Apophis asteroid is approximately the size of two-and-a-half football fields.
99942 Apophis (2004 MN4) is one of the most important near-Earth asteroids ever discovered. It will make a very close Earth approach on Friday, April 13, 2029 when it will pass within 0.1 lunar distances, which is only a few Earth radii above Earth's surface.
5 Μαρ 2024 · On April 13, 2029, the space rock is scheduled to approach Earth, coming within 20,000 miles (32,000 kilometers) of our planet's surface. The event will mark the closest Earth flyby of an...
