Scientists around the world continue to worry about Apophis, an asteroid with a width of 325 meters, discovered in 2004 and named after the ancient Egyptian God of evil, darkness and destruction.
Write about the Sensational news.
As expected, April 13, 2029, Apophis, 99942, or Apophis will be just 37 600 km from Earth one tenth of the distance between the Earth and the Moon, warned researchers from the Department of celestial mechanics in Saint Petersburg.
In the report prepared for the Royal lectures on cosmonautics, to be held in Moscow at the end of this month, scientists report that the asteroid that is moving at a speed of about is 7.43 km per second, with a high probability to hit Earth in the coming decades as it is affected by the gravity of the planet.
“The approach [of the asteroid] causes significant scattering of possible trajectories, among which there are trajectories pointing to the convergence in 2051 year. Future repeat visits to the orbit and contain a large number (about a hundred) possible collision between Apophis and Earth, and the most dangerous of them fall on the year 2068,” reads the report.
According to scientists, St. Petersburg state University, who has paid great attention to the study of Apophis, the asteroid will fly within 16 million kilometers from our planet in 2044, in the range of 760 000 km in the year 2051, within five million in 2060, and within 100,000 km in 2068.
If the asteroid will hit the Earth, it will leave her impact crater with a width of several kilometers, and the force of his stroke is estimated at 2,500 megatons of TNT, which is 50 times larger than the biggest ever exploded nuclear bombs. For comparison, the atomic bomb dropped on Hiroshima in 1945, exploded with a force of about 15 kilotons of TNT.
To Apophis struck the planet, he must pass the Earth at a precise altitude, known as the keyhole, while flying in 2029. According to NASA research, conducted in 2013, there is a keyhole with a width of two meters, which will lead to impact in 2068, but the real chances of a collision are just one of the approximately 2.3 million.
Just in case the scientists of Russia and the USA have developed several options of actions for such unforeseen circumstances, to reduce the risk of collision. In 2016, researchers from Tomsk state University in Siberia used a supercomputer to calculate the way for the safe destruction of Apophis with nuclear charge and to ensure that irradiated fragments will not land on the Ground.
Earlier it was reported how NASA will deal with the asteroids.
