Astronomer from Quebec Gilles Couture conducted a study using computer simulation.
Because of this he was able to prove that early in the Solar system, stars, there was a "duet". But one of them left our galaxy and flew in the space provided, leaving the Sun in splendid isolation.
According to the study, conducted by the astronomer, the weight of the mysterious star was 2-3 times less than that of the Sun, and the speed of its movement ranged from 25 to 100 kilometers per second. The astronomer did not say when the second star was in the Solar system, although, in all probability, it could be a fairly short time.
Apparently, it is the presence of the second the stars in our galaxy were the cause of the unusual elongated shape of the orbits of some planets are in the Kuiper belt beyond Neptune, which contains a huge number of blocks of ice. To affect the orbits of the planets could have some kind of rogue planet, whose mass should be 16 times more than Earth. Previously it was thought that the gravitational pull the orbits of TRANS-Neptunian objects could be due to the existence of the ninth planet. This explained the location of other planets and celestial bodies. in addition, the researchers identified five factors proving the existence of the ninth account of the planet.
Thus, it is usual to all mankind the concept of the existence of one single star in the Solar system, undergoing change. Although scientists assume that the boundary of the Oort Cloud there is another star to watch that every 32 million years. Of course, given such a considerable period of time, it is not surprising that it is still tracking her, no one has.
