Boötes

Boötes is one of the beautiful constellations in the night sky. It is found in the northern sky, between certain angles called declination and right ascension. Its name means "herdsman" or "plowman."

Boötes was first described by the ancient astronomer Ptolemy. It is now one of the 88 official constellations. The constellation contains Arcturus, the fourth-brightest star in the night sky. Arcturus is an orange giant. Another famous star in Boötes is Epsilon Boötis, also called Izar. It is a colorful multiple star that many amateur astronomers enjoy looking at. Boötes has 29 stars that can be seen with the naked eye.
