Its story

59 Persei is a suspected astrometric binary —an apparently single star whose motion across the sky betrays the gravitational tug of an unseen companion. Of class A1Vn, it is a blue-white main-sequence star roughly 256 light-years away, riding the shoulders of Perseus. The «n» in its spectral type marks broadened lines: it spins fast, and its atmosphere carries the smeared signature of that rotation.
