NASA released images of a huge asteroid will approach the Earth at a critical distance. Today, for all astronomers, the Earth’s moment of truth – the asteroid 2015 TV145 as close to our planet, which will allow him to watch with binoculars and telescopes home. But this is not the last visit of the asteroid.

«The next time an asteroid TV145 will return to Earth November 11, 2018. But the three-year journey will make adjustments to the trajectory of celestial bodies: in 2018 an asteroid will pass at a distance of 40 million kilometers, “- said the researcher at the Institute of Applied Mathematics of the Keldysh, Leonid Elenin.

This is the conclusion scientists Recalling 500 measurements made by American astronomers Observatory Pan Starrz in the period from the opening of the asteroid (13 October 2015) to date.

Later visits asteroid is not yet known, but scientists hope that the answer to this the question is found in the course of observations at the time of closest approach of the space object. The only thing that might suggest the scientists is the fact that in the next thirty years, the asteroid does not collide with the Earth. The prognosis is not very positive, given that in 2015 the volume TV145 eight times the Tunguska meteorite, which fell in Siberia at the beginning of XX-th century, and caused enormous damage. The scale of the consequences of the fall of the asteroid to Earth in 2015 TV145 will be incomparably greater consequences of the Tunguska meteorite. Time to the humanity to think of something to prevent such a collision – the big question, if this asteroid was discovered already on approach to Earth (18 days before closest approach).

asteroid can watch the residents of the Urals, Siberia and the central region of Russia. The facility will resemble a bright star with no tail. His movement will be held in the south-east to south-west, at an altitude of about 30 degrees above the horizon (in Moscow, the maximum height will be about 40 degrees above the horizon). But the only thing that will distinguish it from the star – a rather fast movement across the night sky. In the words of the candidate physical and mathematical sciences, the secretary of the expert working group on space threats of the Institute of Astronomy, RAS Sergei Naroenkova, span asteroid “will not cause any anomalies” in the world, but our planet may be its gravitational field affect its trajectory, although the direction of this influence is still unknown.

As you know, it falls to Earth every day a huge number of small celestial bodies. Some of them are not even detected by astronomers. Some of the objects are visible in the form of a star the size of 10-20 centimeters.

«larger celestial body the size of a meter or more in diameter falling to Earth less” – says Naroenkov. For example, such bodies as “Chelyabinsk meteorite” fall once in a hundred years, and the Tunguska – can fly more than once in a hundred years.

According to the scientist, humanity has no choice as to improve their knowledge of establishment of an effective protection against threats of celestial bodies like Tunguska, Chelyabinsk meteorite, asteroid 2015 TV145.
