Campbell's Hydrogen Star is an epic variable star. It sits in the constellation Cyg, shines at apparent magnitude 10 and has spectral type WC....
Its spectrum reads WC... — a Wolf-Rayet star: a stellar monster shedding its own outer layers in a ferocious wind, on its way to a supernova.
Look for Campbell's Hydrogen Star in the constellation Cyg. At apparent magnitude 10, a small backyard telescope will bring it into view.
Like any astronomical target, Campbell's Hydrogen Star 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.
Campbell's Hydrogen Star scores 59 points on Spacedle's rarity scale, which places it in the epic tier. Another 19 points would lift it into a rarer tier.
That score comes from 6 science badges — Variable star, Has a proper name, Wolf-Rayet star (shedding itself), Blue-white star, Gently variable 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.
