Its story

37 Herculis unfolds 294 light-years away within the ancient figure of the kneeling hero, one of the largest constellations of the northern summer sky. It is a multiple A-class system, white and hot, where several stars share the same luminous point to the unaided eye. A telescope is needed to break its seemingly single shine into its individual components —a quiet perspective trick the cosmos plays again and again across the celestial sphere.
