Now, according to preliminary calculations of scientists, the world will face two catastrophic threats from space. We are talking about the asteroid Apophis, the trajectory of which has been of great concern to astrophysicists lately.
According to their calculations, the cosmic body should come close to the Earth twice – in 2029 and 2036.
For the first time, the object will approach the Earth at a distance of only 40 thousand kilometers, but this number may decrease under the gravity of our planet. However, astronomers believe that even in this case, the Earth will avoid a collision with an asteroid.
If we survive this event, then in seven years (in 2036) the asteroid will again approach the Earth, but then the asteroid will fly straight to it.
Astronomers have indicated countries that may be hit by a celestial body: the United States, Russia, China, Japan and Canada. The impact force will be comparable to the 44 atomic bombs dropped on Hiroshima in 1945, which is equal to 800 megatons of TNT.
A hit can set off a chain reaction consisting of a series of monstrous disasters that can wipe out all life from the face of the Earth.
Russian scientists issued encouraging amendments. We are talking about the Yarkovsky effect, the essence of which is the effect of sunlight on the surface of a rotating asteroid. When heated, the warm side of the asteroid will emit more photons than the cold side. The result is a small reactive force that will affect the trajectory of the asteroid and knock it out of the way.
Well, let’s hope that the Sun will help us, otherwise humanity will have to look for more effective ways to solve a global problem
