Astronomers have determined the exact distance to the North star
Astronomers have determined the exact distance to the North star Using data from the Gaia telescope, astronomers have determined the exact distance to the pole star, it is 447+/- 1,6 light-years, reported in the journal Research Notes of the American Astronomical Society. In addition, the researchers also revised the radius, age and mass of stars. Despite the fact that the polar star is one of the most famous stars in the sky, which is mentioned in the catalogue of stars of “Almagest” compiled by Ptolemy almost two thousand years ago, scientists still could not accurately determine the distance to it. Modern estimates give a range of values from 322 to 520 light years, which also bothered to study the properties of stars. But now, thanks to a new data release of the Gaia telescope, published in April, astronomers were able to obtain the exact value. In fact the North star
