Its story

39 Herculis is a yellow-white F-type star burning at 143 light-years within Hercules, the kneeling hero of the summer sky. Slightly hotter and more luminous than the Sun, it shares its sky with the famous globular cluster M13, one of the densest in the northern hemisphere. Its light looks onto a constellation through which the entire solar system slowly drifts: the Sun is heading toward this neighborhood, the so-called solar apex.
