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 ...
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.
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 ...
If approved, it is expected to be launched in April 2028, to arrive at Apophis in February 2029, before its closest approach to Earth. It will conduct multiple measurements of the asteroid's properties, to study possible response in case such an asteroid would be on a collision course with Earth. [1] [2] [3] [clarification needed]
Trajectory of 2004 FH in the Earth–Moon system Goldstone radar images of asteroid 2007 PA 8 's Earth flyby in 2012. This is a list of examples where an asteroid or meteoroid travels close to the Earth. Some are regarded as potentially hazardous objects if they are estimated to be large enough to cause regional devastation.
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.
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 [update] , 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 .
