16 Persei (HIP 13254)

16 Persei is a white main-sequence star in the constellation Perseus. At 121 light years away, it shines at an apparent visual magnitude of 4.22. 16 Persei is the primary component of a multiple-star system. The star's age is estimated to be 1 billion years but is certainly no less than 900 million years and no greater than 1.1 billion years. The iron abundance of 16 Persei is -0.04 (91.2% of the Sun). It is moving through the Galaxy at a speed of 41.8 km/s relative to the Sun. Its projected Galactic orbit carries it between 19,100 and 25,100 light years from the center of the Galaxy.
