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.
Additional observations of Apophis have allowed astronomers to long rule out the risk of an impact in 2029 when Apophis is predicted to come within a distance of Earth 10 times closer than the ...
"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.
There is a point between the Earth and Sun where the gravities of the two bodies are perfectly in balance, called the Sun-Earth L1 Lagrange point (SEL1). It is approximately 1.6 million kilometres (1 million miles) from Earth, about four times as far away as the Moon, and is ideally suited for placing such a space telescope. [13]
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.

Asteroid 2024 YR4’s rating of 3 may be the second-highest an asteroid has ever reached after the notorious Apophis briefly hit a rating of 4 many years ago, but future data is expected to drop ...
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.
