HR 985 is a rare variable star. It lies about 762 light-years from Earth, sits in the constellation Cam, shines at apparent magnitude 4.74 and has spectral type B2.5Vne.
Its spectrum reads B2.5Vne — 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 HR 985 in the constellation Cam. At apparent magnitude 4.74, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, HR 985 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 985 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 9 science badges — Variable star, Naked-eye visible, Never sets (northern circumpolar), Hot blue B-type star, Main-sequence star, Blue-white star, Intrinsically luminous (Mv < −2) and Barely variable (under 0.05 mag) — 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.
