What is Pi Persei
Pi Persei is a white A-type star roughly 310 light-years away, set in the rich background of Perseus, that constellation heavy with open clusters and the legendary Algol. It shines in a region crossed by the winter Milky Way, thick with young suns and gas clouds. Its clean white light is one among the many that trace the shoulders and cloak of the Greek hero.
