Its story
ζ Boötis lies within the Herdsman, not far from amber Arcturus. It is a multiple system 176 light-years away: two blue-white stars circling each other every 125 years, joined by a more distant third companion. Its crisp light comes from young A3 subgiants, hot and quickly rotating, still far from maturity.
