Boötes, pronounced with both 'O's as 'boötez', is one of the 88 modern constellations in the northern sky. The name is from the Greek word Βοώτης, which means herdsman – someone who takes care of animals.
The constellation's shape is like a kite. Boötes has the third brightest star in the night sky, called Arcturus (α Bootis). The astronomer Ptolemy listed it in the 2nd century when he made a list of 48 constellations.
