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.
In the case of Apophis, further observations eventually allowed astronomers in 2021 to rule out the possibility of an impact when the asteroid makes a close flyby to Earth in 2029 and again in ...
Asteroid (35396) 1997 XF 11 will pass 930,000 km (0.0062 AU) from the Earth. 2029 NASA's New Horizons spacecraft will exit the Kuiper Belt. [4] 2029 April 13 Near-Earth asteroid (99942) Apophis will pass Earth at a relatively small distance of 31,200 km (19,400 mi) above Earth's surface, closer than some geosynchronous satellites.

A small Solar System body can be an asteroid or a comet, thus an NEO is either a near-Earth asteroid (NEA) or a near-Earth comet (NEC). The organisations cataloging NEOs further limit their definition of NEO to objects with an orbital period under 200 years, a restriction that applies to comets in particular, [ 2 ] [ 26 ] but this approach is ...
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 ...
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. [ 8 ] A retrograde parabolic Oort cloud comet (e=1, i=180°) could pass Earth at 72 km/s when 1 AU from the Sun.
