Sadr is an epic star. It lies about 1,832.3 light-years from Earth, sits in the constellation Cyg, shines at apparent magnitude 2.23 and has spectral type F8Ib.
Its spectrum reads F8Ib — an F-type star — a little hotter, whiter and shorter-lived than the Sun.
Look for Sadr in the constellation Cyg. At apparent magnitude 2.23, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, Sadr 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.
Sadr scores 66 points on Spacedle's rarity scale, which places it in the epic tier. Another 12 points would lift it into a rarer tier.
That score comes from 7 science badges — Star, Distant (over 1,000 light-years), Naked-eye visible, Has a proper name, Yellow-white F-type star, Supergiant and Blindingly luminous (Mv < −5) — 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.
