#lambda sagittarii

Sagittarius, which is Latin for "archer," is one of the original 48 constellations set down by Greek astronomer Ptolemy. The brightest stars form an asterism known as "the Teapot." However, in older drawings, the teapot area is usually drawn as the bow and arrow.

In most mythologies, Sagittarius is seen as a centaur and archer. The Babylonians saw Sagittarius as the centaur, the god Nergal. However, Nergal has wings and two heads, one a panther head, the other a human head. In Greek mythology, Sagittarius is still a centaur in the true meaning of the word: half horse, half man. Some myths see him specifically as Chiron, the wisest of all the centaurs.

The named stars, in order of brightness are:
