99942 Apophis (provisional designation 2004 MN4) is a near-Earth asteroid and a potentially hazardous object with a diameter of 370 metres (1,210 feet) [ 3 ] that caused a brief period of concern in December 2004 when initial observations indicated a probability up to 2.7% that it would hit Earth on April 13, 2029.
Apophis is of interest because it’s an S-type, or stony, asteroid — different from other space rocks visited by NASA missions, including Bennu, which is a C-type, or carbonaceous, asteroid.
Ramses, or Rapid Apophis Mission for Space Safety, is a proposed ESA mission to a near-Earth asteroid 99942 Apophis.If approved, it is expected to be launched in April 2028, to arrive at Apophis in February 2029, before its closest approach to Earth.
OSIRIS-REx in Launch Configuration. OSIRIS-REx[ a ] was a NASA asteroid-study and sample-return mission that visited and collected samples from 101955 Bennu, a carbonaceous near-Earth asteroid. [ 14 ] The material, returned in September 2023, is expected to enable scientists to learn more about the formation and evolution of the Solar System ...
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 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 ...
Satellites in geostationary orbit. From the list in the first section, these are the closest known asteroids per year that approach Earth within one lunar distance.More than one asteroid per year may be listed if its geocentric distance [note 1] is within a tenth of the lunar distance, or 0.10 LD.
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 ...
