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.
September 13, 2024 at 10:58 AM. In a bit of ominous news befitting a Friday the 13th: It turns out that the asteroid Apophis could have a very small chance of colliding into Earth in five years ...
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.
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 impact prediction is the prediction of the dates and times of asteroids impacting Earth, along with the locations and severities of the impacts. The process of impact prediction follows three major steps: Discovery of an asteroid and initial assessment of its orbit which is generally based on a short observation arc of less than 2 weeks.
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 ...
In the same year, NASA released a study where the asteroid Apophis (with a diameter of around 300 meters or 1,000 feet) was assumed to have a much lower rubble pile density (1,500 kg/m 3 or 100 lb/cu ft) and therefore lower mass than it is now known to have, and in the study, it is assumed to be on an impact trajectory with Earth for the year ...
Apophis, a near-Earth object estimated to be about 1,100 feet across, was previously identified as an object of concern. But, any risk that it could impact Earth has been ruled out, as well as the ...
