9 Cep is a rare variable star. It sits in the constellation Cep, shines at apparent magnitude 4.76 and has spectral type B2Ib.
Its spectrum reads B2Ib — a blue-white B-type star, with a surface tens of thousands of degrees hot and a life measured in tens of millions of years.
Look for 9 Cep in the constellation Cep. At apparent magnitude 4.76, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, 9 Cep 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.
9 Cep scores 46 points on Spacedle's rarity scale, which places it in the rare tier. Another 4 points would lift it into a rarer tier.
That score comes from 7 science badges — Variable star, Naked-eye visible, Never sets (northern circumpolar), Hot blue B-type star, Supergiant, Barely variable (under 0.05 mag) 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.
