Features

The star belongs to the class of yellow-orange dwarfs of the main sequence . Its mass is almost the same as that of the Sun , and its diameter is 1.07 solar ^[3] . The luminosity of a star is 1.01 of the luminosity of the Sun. According to studies of the magnetic activity of a star ^[4] , its age is estimated at approximately 600 million years — the young star was by astronomical standards.
