Zeta Sagittarii (ζ Sagittarii, abbreviated Zeta Sgr, ζ Sgr) is a triple star system and the third-brightest star in the constellation of Sagittarius after Kaus Australis and Nunki. Based upon parallax measurements, it is about 88 light-years (27 parsecs ) from the Sun .
[1] [2] 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. These same stars originally formed the bow and arrow of Sagittarius. [3]
Alpha Sagittarii is a blue, class B dwarf star.It does not appear particularly bright in the sky to the naked eye, with a visual apparent magnitude of +3.97.. The star has an effective temperature about twice that of the Sun and is nearly three times as massive, with a luminosity about 130 times that of the Sun. Based on an excess emission of infrared radiation, it may have a debris disk, much ...

Phi Sagittarii, Latinized from φ Sagittarii, is a binary star in the southern constellation of Sagittarius. With an apparent visual magnitude of 3.17, [2] it is the ninth-brightest star in the constellation and is readily visible to the naked eye. Parallax measurements place it at a distance of roughly 239 light-years (73 parsecs) from the ...
Sigma Sagittarii has a spectrum matching a stellar classification of B2.5 V, [4] which indicates this is a B-type main-sequence star.Its total luminosity is 3,300 [16] times that of the Sun while it has a surface temperature of 18,890 K. [9] X-ray emission has been detected from this star, which has an estimated X-ray luminosity of 1.2 × 10 28 erg s −1.
