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.


Myths regarding Sagittarius are varied. In Greek mythology, Sagittarius is sometimes described as a centaur that was placed in the sky to help guide Jason and the Argonauts, a group of Greek warriors. Other times the constellation is associated with Crotus, son of the god Pan and an excellent hunter and musician.
