    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, 13 April 2029.

    The average near-Earth asteroid, such as 2019 VF 5, passes Earth at 18 km/s. The average short-period comet passes Earth at 30 km/s, and the average long-period comet passes Earth at 53 km/s. [10] A retrograde parabolic Oort cloud comet (e=1, i=180°) could pass Earth at 72 km/s when 1 AU from the Sun.

    The 1992 NASA-sponsored Near-Earth-Object Interception Workshop hosted by Los Alamos National Laboratory evaluated issues involved in intercepting celestial objects that could hit Earth. [27] In a 1992 report to NASA, [28] a coordinated Spaceguard Survey was recommended to discover, verify and provide follow-up observations for Earth-crossing ...

    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.

  8. Yarkovsky effect - Wikipedia

    en.wikipedia.org/wiki/Yarkovsky_effect

    In 2020, astronomers confirmed Yarkovsky acceleration of the asteroid 99942 Apophis. The findings are relevant to asteroid impact avoidance as 99942 Apophis was thought to have a very small chance of Earth impact in 2068, and the Yarkovsky effect was a significant source of prediction uncertainty.

  9. Asteroid impact prediction - Wikipedia

    en.wikipedia.org/wiki/Asteroid_impact_prediction

    In 1998, NASA formally embraced the goal of finding and cataloging, by 2008, 90% of all near-Earth objects (NEOs) with diameters of 1 km or larger that could represent a collision risk to Earth. The 1 km diameter metric was chosen after considerable study indicated that an impact of an object smaller than 1 km could cause significant local or ...
