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.
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 ...
Apophis in particular has the 2029 "keyhole" issue - it is definitely under active observation to determine whether it will pass through that area which would cause an impact in 2036. Using the guidance from article notability that "notability is not temporary", any asteroid which has been Torino Scale 1 should continue to be considered ...
Initially, astronomers were concerned that the space rock might impact Earth in 2029 and 2068, but subsequent observations have ruled out any risk of Apophis posing a threat to the Earth for the ...
The location of 2024 YR4 qualifies it not just as any asteroid, but a near-Earth object (NEO). NEOs are defined as asteroids that hug the inner solar system, where we live, coming within 1.3 ...

A similar scenario unfolded in 2004 with Apophis, an asteroid initially projected to have a 2.7 percent chance of striking Earth in 2029. Further observations ruled out an impact. "City killer ...
The minimum orbit intersection distance (MOID) between an asteroid and the Earth is the distance between the closest points of their orbits. This first check is a coarse measure that does not allow an impact prediction to be made, but is based solely on the orbit parameters and gives an initial measure of how close to Earth the asteroid could ...
