Planetary scientists have admitted the existence of a second Mars in the Solar system

In the Kuiper belt, located farther from the Sun than all of the currently known planet, can be the outer body, the size and mass like Mars. If the assumption is confirmed, it will mean that the Solar system is nine, and probably ten planets.

Representatives of the University of Arizona Katrin Wolf and Ren Malhotra came to the conclusion that, based on the movement of various objects in the Kuiper belt, the hypothetical “second Mars”, may cause gravitational effects otherwise the tilt of their orbits would be different. Is while not directly detected planet, according to researchers, 50 times farther from the Sun than the Earth. On the obtained findings, the scientists said in the pages of scientific publications of The Astronomical Journal.

Currently humanity “certainly” aware of the existence of the eight planets of the Solar system are terrestrial planets mercury, Venus, Earth and Mars, the gas giants Jupiter and Saturn and ice giants Uranus and Neptune. From 1930 to 2006, Pluto was considered, however, in the late XX and early XXI century in the outer part of the Solar system was discovered many objects that are not too different from it by mass (or more massive than Pluto, Eris), then the term “planet” was given a clearer definition. Pluto under this definition were not included, as close to its orbit is not a “space, free from other bodies.” Thus, even if a hypothetical object exists and is indeed reminiscent in size of Mars, it does not mean that he is surely a “planet” in the strict sense of the word.

Last year, experts are actively discussing the potential discovery of another planet in the Solar system. We are talking about the so-called “planet X”, the existence of which was theoretically justified in the beginning of last year by astronomers Michael brown and Konstantin Batygin. As shown by calculations of scientists, this planet should be about 10 times heavier than Earth and have a 2-4 times larger diameter than ours, and a complete revolution around the Sun to make 15-20 thousand years. However, to directly observe this celestial body scientists have not yet succeeded, and some have suggested that in fact it does not exist.
