3 Sgr is an epic variable star. It lies about 985.4 light-years from Earth, sits in the constellation Sgr, shines at apparent magnitude 4.53 and has spectral type F7II.
Its spectrum reads F7II — an F-type star — a little hotter, whiter and shorter-lived than the Sun.
Look for 3 Sgr in the constellation Sgr. At apparent magnitude 4.53, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, 3 Sgr is best seen from a dark site away from city lights, and when it is above the horizon depends on your latitude and the time of year. The visibility panel above works out tonight's viewing window for your saved location.
3 Sgr scores 62 points on Spacedle's rarity scale, which places it in the epic tier. Another 16 points would lift it into a rarer tier.
That score comes from 9 science badges — Variable star, Naked-eye visible, Toward the galactic centre, On the zodiac, Yellow-white F-type star, Bright giant, Intrinsically luminous (Mv < −2) and Strongly variable — each earned for a real, measurable property of the object. Rarity on Spacedle is never random: the more remarkable an object's astrophysics, the more badges it collects, the higher it scores, and the rarer it ranks.
