Scientists have defined exact distance to the Pole star


It makes 447/-1,6 light years. It was succeeded to count him thanks to the data obtained from the Gaia telescope. Astronomers for the first time could establish what distance from Earth to the Pole star. It makes 447/-1,6 light years. It is reported in the Research Notes of the American Astronomical Society magazine. It is known that scientists have revised age, the weight and radius of a star. So far the exact distance to her didn't manage to be defined. The dispersion of values was from 322 to 529 light years. It is also known that the Pole star represents system from three stars. The first is a supergiant around which two stars of the smaller sizes - Polar B and Polar Ab (or P). rotate Besides, the main properties of a star have been established. Its radius is equal 47-50 solar, and weight - to 6,4-6,7 mass of the Sun. At the same time the age is 55-65 million years. Thanks to these data it was succeeded to establish that the Pole star, most likely, for the first time crosses a strip of the pulsation instability on the chart Gertsshprunga-Russell. There is it when stars descend from the main sequence. Earlier it was reported that the star which absorbs planets has been found. She is located in 450 light years from Earth.
