The mysterious asteroid was called the alien probe


Interstellar asteroid of Oumuamua
Scientists of Harvard University recognized as probable the version according to which the interstellar asteroid of Oumuamua is a space sail — the alien probe which accelerates, using pressure of ions of solar wind. However, according to researchers, inexplicable acceleration of an asteroid can have the natural reasons. It is reported in the press release on Phys.org. The Oumuamua — the first interstellar object which the person managed to find. The asteroid of a cigar-shaped form reaches in length of 400 meters, and in the diameter — about 30 meters. An object has been found on October 19, 2017 at distance 0,2 astronomical units from Earth (a quarter of distance between the Sun and Earth). Scientists have defined that Oumuamua contained a lot of ice though signs of decontamination weren't observed when passing an asteroid near a star. When an object has begun to leave Solar system, his speed has unexpectedly increased, but wasn't slowed down as astronomers expected. The decontamination caused by emissions of gases because of heating by sunshine was the most probable explanation of change of speed. However scientists from Harvard have called this version in question as decontamination wasn't observed when the asteroid was closer to the Sun. Besides, similar process would lead to change of rotation of a celestial body, and it was revealed not. According to a new hypothesis, Oumuamua I have accelerated because of sunlight pressure. However at the same time the celestial body has to be extremely thin in relation to diameter of his surface. A similar object has to be either artificial origin, or natural, but in the latter case the possible mechanism of his formation remains to unknown. A number of scientists don't agree with this statement. According to Alan Fittssimmons (Alan Fitzsimmons), the astrophysicist from the Queens University (Northern Ireland), observed properties of an asteroid will be agreed with the expected behavior of the kometopodobny bodies which are thrown out from other planetary system.
