31 Cyg is a rare variable star. It lies about 883.9 light-years from Earth, sits in the constellation Cyg, shines at apparent magnitude 3.8 and has spectral type K2II+....
Its spectrum reads K2II+... — a K-type star. Orange K dwarfs are the marathon runners of the galaxy, burning steadily for tens of billions of years.
Look for 31 Cyg in the constellation Cyg. At apparent magnitude 3.8, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, 31 Cyg 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.
31 Cyg scores 45 points on Spacedle's rarity scale, which places it in the rare tier. Another 5 points would lift it into a rarer tier.
That score comes from 7 science badges — Variable star, Naked-eye visible, Orange K-type star, Bright giant, 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.
