Bo÷tes (abbr. Boo, gen. Bo÷tis)





The Herdsman; a large, kite-shaped constellation of uncertain mythological provenance that is dominated by Arcturus, the brightest star in the northern hemisphere. Bo÷tes borders on Canes Venatici and Coma Berenices to the west, Virgo to the south, Serpens, Corona Borealis, and Hercules to the east, Draco to the north, and Ursa Major to the northwest. It is home to the prototype Lambda Bootis star and also contains Xi Bootis, an easily-seen binary with yellow and orange components of magnitude 5 and 7, respectively, that is also a BY Draconis star. See below for details of the constellation's brightest stars.
