HR 8164 is a rare variable star. It lies about 1,929.9 light-years from Earth, sits in the constellation Cep, shines at apparent magnitude 5.51 and has spectral type B3Vv comp.
Its spectrum reads B3Vv comp — 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 8164 in the constellation Cep. At apparent magnitude 5.51, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, HR 8164 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 8164 scores 48 points on Spacedle's rarity scale, which places it in the rare tier. Another 2 points would lift it into a rarer tier.
That score comes from 9 science badges — Variable star, Distant (over 1,000 light-years), Naked-eye visible, Never sets (northern circumpolar), Hot blue B-type star, Main-sequence star, Intrinsically luminous (Mv < −2) and Gently variable — 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.
