Apophis quickly gained notoriety as an asteroid that could pose a serious threat to Earth when astronomers predicted that it would come uncomfortably close in 2029. Thanks to additional observations of Apophis, the risk of an impact in 2029 was later ruled out, as was the potential impact risk posed by another close approach in 2036.
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.
Mar 26, 2021 · After its discovery in 2004, asteroid 99942 Apophis had been identified as one of the most hazardous asteroids that could impact Earth. But that impact assessment changed as astronomers tracked Apophis and its orbit became better determined.
May 10, 2024 · In just under half a decade, a 1,000-foot-wide (305-meter-wide) asteroid named after the Egyptian god of chaos and destruction, Apophis, will pass within 30,000 miles (48,300 kilometers) of...
Mar 27, 2021 · Nasa had deemed Apophis to be one of the most dangerous asteroids to Earth after its discovery in 2004. Close calls in 2029 and 2036 were predicted and later ruled out. A slight threat still...
Jul 4, 2024 · Asteroids once ended the life of dinosaurs on earth, triggering an extinction level event that still haunts many people. There is a massive asteroid dubbed 99942 Apophis which is a near-Earth object (NEO) and it is believed that this may reach Earth in 2029. The size of the asteroid is 1,1100 feet or 335 metres in size, NASA confirmed.
Mar 25, 2021 · March 25, 2021. The near-Earth object was thought to pose a slight risk of impacting Earth in 2068, but now radar observations have ruled that out. After its discovery in 2004, asteroid 99942 Apophis had been identified as one of the most hazardous asteroids that could impact Earth.
May 31, 2022 · The exercise focused on the real asteroid Apophis. For a short while after its discovery in 2004, Apophis was assessed to have a significant chance of impacting Earth in 2029 or later.
On 13 April 2029, asteroid Apophis will come within 32 000 km of Earth’s surface. It will be the closest approach of an asteroid of this size that humankind has ever known about in advance. During the approach, Apophis will be significantly affected by Earth’s mighty gravity.
Researchers at NASA/JPL, Caltech, and Arecibo Observatory have released the results of radar observations of the potentially hazardous asteroid 99942 Apophis, along with an in-depth analysis of its motion.
