HR 5223 is an epic variable star. It sits in the constellation Cen, shines at apparent magnitude 5.83 and has spectral type B2IIIe.
Its spectrum reads B2IIIe — 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 5223 in the constellation Cen. At apparent magnitude 5.83, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, HR 5223 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 5223 scores 53 points on Spacedle's rarity scale, which places it in the epic tier. Another 25 points would lift it into a rarer tier.
That score comes from 8 science badges — Variable star, Naked-eye visible, Hot blue B-type star, Giant star, Blue-white star, Gently variable, Fades out of naked-eye view 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.
