HR 8157 is an epic variable star. It lies about 2,160 light-years from Earth, sits in the constellation Cyg, shines at apparent magnitude 5.89 and has spectral type F2Ib.
Its spectrum reads F2Ib — an F-type star — a little hotter, whiter and shorter-lived than the Sun.
Look for HR 8157 in the constellation Cyg. At apparent magnitude 5.89, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, HR 8157 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.
HR 8157 scores 57 points on Spacedle's rarity scale, which places it in the epic tier. Another 21 points would lift it into a rarer tier.
That score comes from 8 science badges — Variable star, Distant (over 1,000 light-years), Naked-eye visible, Yellow-white F-type star, Supergiant, Intrinsically luminous (Mv < −2), Gently variable and A named variable star — 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.
