The asteroid Apophis, discovered in 2004 and named after the ancient Egyptian god of evil and destruction, caused turmoil among scientists who revealed that there is a 2.7 percent possibility of collision with the Earth in 2029. This possibility was dismissed later, but astronomers have not ruled out the threat of a collision in 2068.
The likelihood of a collision with Apophis in the present century is minimal, according to a study conducted during NASA’s radar observation campaign.
According to the research, on 5 March, the celestial object, around 1,100 feet (340 meters) across, approached our planet at a distance of about 10.6 million miles (17 million kilometers) and even this great instance (44 times more distant than the Moon) offered astronomers the opportunity to conduct far more accurate calculations through the use of a 230-foot (70-meter) radio antenna at the Deep Space Network’s Goldstone Deep Space Communications Complex near Barstow, California.
New data has further reduced uncertainty in the orbit of Apophis “from hundreds of kilometers to just a handful of kilometers when projected to 2029.”
Apophis was put at the CNEOS risk list, which now includes 21 asteroids that could possibly hit the Earth within the next 100 years, 17 years ago.
Apophis is expected to get extremely close to our planet in April 2029, passing by less than 20,000 miles (32,000 kilometers) from the Earth’s surface, closer than some geosynchronous satellites. The celestial body with the form of a peanut could be seen with the unaided eye from Earth’s eastern hemisphere.
Earlier, astronomers said that an explosion from possible collision with Apophis in 2068 would be “the equivalent of 1,200 million tons of TNT or about 80,000 Hiroshima nuclear bombs.”
