A bright zodiac constellation in the southern hemisphere, represented as a centaur aiming a bow and arrow at neighboring Scorpius.

The sun passes through Sagittarius from mid-December to mid-January, including the winter solstice, when it is farthest south of the equator. The constellation contains many nebulae and globular clusters, and open star clusters.

Kaus Australis and Nunki are its brightest stars. The center of our galaxy, the Milky Way, is marked by the radio source Sagittarius A.
