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.
Further observations eventually allowed astronomers in 2021 to rule out the possibility of an impact when Apophis makes the close flyby to Earth in April 2029. There's also no risk during another ...
These images represent radar observations of Apophis on March 8, 9 and 10, 2021, as it made its last close approach before its 2029 Earth encounter. The data ruled out any chance of Earth impact ...
Jet Propulsion Laboratory scientists Lance Benner, Paul Chodas and Mark Haynes are studying the 1,100-foot wide asteroid Apophis, which will come within viewing distance of Earth on April 13, 2029.
The close approach of 99942 Apophis (previously better known by its provisional designation 2004 MN 4) to the Earth and Moon on April 13, 2029. The white bar indicates uncertainty in the range of possible positions as of the 2007 observation data. The 2029 uncertainty region is now down to ±700 km. See also: :Image:2004mn4d4 s.gif.
In December 2004 when Apophis was estimated to have a 2.7% chance of impacting Earth on 13 April 2029, the uncertainty region for this asteroid had shrunk to 82,818 km. [74] Response to predicted impact
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 close approach of the asteroid Apophis to the Earth and Moon on Friday, April 13, 2029. Ramses, or Rapid Apophis Mission for Space Safety, is a proposed European Space Agency (ESA) mission to a near-Earth asteroid 99942 Apophis. If approved, it is expected to be launched in April 2028 and to arrive at Apophis in February 2029 before its ...
