The red star with a magnitude of 8.8 is still visible through a telescope, in the close vicinity of our Sun. It is only 13 light-years away from it and exhibits the largest proper motion - 8.7 arc seconds per year - after Barnard's Star. Its position will change by the diameter of the Moon in two centuries. This rapid motion, in space at a speed of 280 km/s, was discovered in 1897 by the Dutch astronomer Jacobus C. Kapteyn, after whom the star is named. Its luminosity is 50 times smaller than that of the Sun. |
