We prove the status of Pluto as a dwarf planet
Astronomer Jean-Luc Margot of the United States proposed a quantitative criterion, which allows you to check the status of a planet from a celestial body (such as Pluto), which is located around its star. The results of their research published in the author resource arXiv.org, and brief them can be found at the University of California in Los Angeles.
To determine the status of a celestial body is sufficient knowledge of three parameters: the mass of the star, the planet's mass and its period of revolution around the sun. Margot method uses a record of how long the celestial body clears its orbit around the parent star and is applicable to extrasolar planets.
Currently, about 5,000 of these objects it allows 99 percent classified as a planet. To elucidate the nature of other bodies of the scientists is not enough data. In our solar system approach Margot reserves Ceres, Pluto and Eris dwarf planet status.
"The gap between the planets and neplanetami strikes. The sharp difference suggests a fundamental difference in the way these bodies were formed, and the fact of their classification shows something deeper about the nature ", - he shared his impressions planetary Margot.
Determination of the planet, proposed by the International Astronomical Union (IAU), is applicable only to the celestial bodies in the solar system. According to him, the planet is considered rounded massive body, clear the neighborhood of its orbit by a large number of smaller bodies.
Total in the solar system, the MAC recognizes the existence of the six dwarf planets. One of them (Ceres) is located in the asteroid belt between the orbits of Mars and Jupiter, while others, like Pluto - orbit beyond Neptune. The largest of them is Pluto.
It is the decision of the MAC in 2006, it ceased to be a planet because it does not satisfy one of its defining criteria (dominance in the space of its orbit). Total in the solar system, according to MAC, there are eight planets. The biggest and most massive of them - Jupiter.
