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.
And the odds that such an impact would send it hurtling toward Earth in 2029 was even lower, at one-in-2-billion, Wiegert wrote. What to know about Apophis: City-killing asteroid to make close ...
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 ...
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 ...
Asteroid impact prediction is the prediction of the dates ... In December 2004 when Apophis was estimated to have a 2.7% chance of impacting Earth on 13 April 2029, ...
This is a list of asteroids that have impacted Earth after discovery and orbit calculation that predicted the impact in advance. As of December 2024, all of the asteroids with predicted impacts were under 5 m (16 ft) in size that were discovered just hours before impact, and burned up in the atmosphere as meteors.
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.
It is a near-Earth asteroid that received minor attention in late September and early October 2006 because initial observations indicated a higher than usual probability that it would strike the Earth in 2029. However, the Near-Earth Object (NEO) Office at NASA's Jet Propulsion Laboratory (JPL) removed 2006 SU 49 from its risk list as ...
