HR 7628 is a rare star. It lies about 1,109.4 light-years from Earth, sits in the constellation Cyg, shines at apparent magnitude 5.46 and has spectral type B5V.
Its spectrum reads B5V — 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 7628 in the constellation Cyg. At apparent magnitude 5.46, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, HR 7628 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 7628 scores 40 points on Spacedle's rarity scale, which places it in the rare tier. Another 10 points would lift it into a rarer tier.
That score comes from 7 science badges — Star, Distant (over 1,000 light-years), Naked-eye visible, Hot blue B-type star, Main-sequence star, Blue-white star and Intrinsically luminous (Mv < −2) — 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.
