ĭelta Sagittarii (δ Sgr) ("Kaus Meridionalis"), is a K2 spectra star with magnitude 2.71 about 350 light years from Earth. Zeta Sagittarii (ζ Sgr) ("Ascella"), with apparent magnitude 2.61 of A2 spectra, is actually a double star whose two components have magnitudes 3.3 and 3.5. "Nunki" is a Babylonian name of uncertain origin, but thought to represent the sacred Babylonian city of Eridu on the Euphrates, which would make Nunki the oldest star name currently in use. Nunki is a B2V star approximately 260 light-years away. Sigma Sagittarii (σ Sgr) ("Nunki") is the constellation's second-brightest star at magnitude 2.08. Instead, the brightest star is Epsilon Sagittarii (ε Sgr) ("Kaus Australis," or "southern part of the bow"), at magnitude 1.85. It is towards the bottom center of the map as shown. Α Sgr (Rukbat, meaning "the archer's knee" ) despite having the "alpha" designation, is not the brightest star of the constellation, having a magnitude of only 3.96. Above this line one sees Corona Australis.
The line going to the right connects ζ to α and β Sagittarii. By approximately 2700 AD, the Sun will be in Scorpius at the winter solstice.
In classical antiquity, Capricorn was the location of the Sun at the winter solstice, but due to the precession of the equinoxes, this had shifted to Sagittarius by the time of the Roman Empire.

The June full moon appears in Sagittarius. In June, it achieves opposition and can be seen all night. By March, Sagittarius is rising at midnight. It is hidden behind the Sun's glare from mid-November to mid-January and is the location of the Sun at the winter solstice (December 21). In southern Brazil, South Africa, and central Australia (30° south), Sagittarius passes directly overhead. In Scotland and Scandinavia it cannot be seen at all. Sagittarius is one of the prominent features of the summer skies in the northern hemisphere although in Europe north of the Pyrenees it drags very low along the horizon and can be difficult to see clearly. Kaus Media bisects Lambda Sagittarii (λ Sgr) and Epsilon Sagittarii (ε Sgr), whose names Kaus Borealis and Kaus Australis refer to the northern and southern portions of the bow, respectively. Fittingly, Gamma2 Sagittarii is Alnasl, the Arabic word for "arrowhead", and Delta Sagittarii is called Kaus Media, the "center of the bow," from which the arrow protrudes. Following the direct line formed by Delta Sagittarii (δ Sgr) and Gamma2 Sagittarii (γ 2 Sgr) leads nearly directly to Antares.
Sagittarius famously points its arrow at the heart of Scorpius, represented by the reddish star Antares, as the two constellations race around the sky. The constellation as a whole is often depicted as having the rough appearance of a stick-figure archer drawing its bow, with the fainter stars providing the outline of the horse's body. To complete the teapot metaphor, under good conditions, a particularly dense area of the Milky Way can be seen rising in a north-westerly arc above the spout, like a puff of steam rising from a boiling kettle. Marking the bottom of the teapot's "handle" (or the shoulder area of the archer), is the bright star (2.59 magnitude) Zeta Sagittarii (ζ Sgr), named Ascella, and the fainter Tau Sagittarii (τ Sgr). These same stars originally formed the bow and arrow of Sagittarius. The stars δ Sgr (Kaus Media), ε Sgr (Kaus Australis), ζ Sgr (Ascella), and φ Sgr form the body of the pot λ Sgr (Kaus Borealis) is the point of the lid γ 2 Sgr (Alnasl) is the tip of the spout and σ Sgr (Nunki) and τ Sgr the handle. The Milky Way is the "steam" coming from the spout.Īs seen from the northern hemisphere, the constellation's brighter stars form an easily recognizable asterism known as "the Teapot".
