What is 1 Boötis

1 Boötis opens the numbering of the Herdsman, that northern human figure who seems to guide Ursa Major across the sky. It is a white A-class star about three hundred and twenty-eight light-years away, removed from the famous glow of Arcturus —the orange giant that rules the constellation. Its modest brightness plays a quiet but symbolic role: being the first in the catalogue of one of the sky’s oldest constellations.

Where it is and when to see it

1 Boötis lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is April, when it culminates around midnight.
