Sagittarius is a large constellation in the Southern Hemisphere. It is best seen in August, which means it is visible during the summer at northern latitudes and during the winter at southern latitudes.

Eight of the brightest stars in Sagittarius form a distinctive teapot shape, which is often used to identify the constellation. The center of the Milky Way galaxy lies close to Sagittarius.

Sagittarius is one of the twelve constellations of the zodiac.
