In the past on the territory of the Solar system for a while could be a star, several times more light than the Sun. With such an assumption was made by canadian researcher Gilles Couture from Quebec University in Montreal. According to him, some time later the second star continued his journey through space, however, changed the orbits of some celestial bodies are reminiscent of her “visit” until now.
According to experts, the speed of movement of the stars, appeared on the territory of the Solar system ranged from 25 to 100 kilometers per second. As shown by a trained computer model under the gravitational influence of such a star could be some cosmic bodies beyond the orbit of Neptune, from-for what the trajectory of their movement along the orbit has changed markedly. So some have indeed observed anomalies concerning transneptunian objects could be explained by the fact that in the past in the Solar system “hosted” another star, says Couture.
At the moment the study was not published in any peer-reviewed scientific publication, however, it available in the digital library of preprints at Cornell University arXiv.org.
Some experts today suggest that the unusual orbit of some objects in the Kuiper belt is explained by the presence in the Solar system, ninth planet in the press it is often called “planet x”. However, while the evidence in favor of the existence of the cosmic body are only indirect and not convincing to all researchers. However, according to Konstantin electrically from the California Institute of technology in Pasadena, for the first time declared “the planet number nine” at the beginning of last year, its presence could provide the most plausible explanation for at least five different phenomena observed in the Solar system. According to existing ideas, “planet X” weighs about 10 times more Land, located in 41 billion kilometers from the Sun and makes a complete revolution around the sun approximately for 15 thousand earthly years, and its orbit is angled about 30 degrees relative to the earth.
