HD 21280 is an epic variable star. It lies about 3,166.6 light-years from Earth, sits in the constellation Per, shines at apparent magnitude 9.15 and has spectral type C0e.
Its spectrum reads C0e — a carbon star, wrapped in so much soot that its light is filtered to a deep ruby red.
Look for HD 21280 in the constellation Per. At apparent magnitude 9.15, a small backyard telescope will bring it into view.
Like any astronomical target, HD 21280 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.
HD 21280 scores 56 points on Spacedle's rarity scale, which places it in the epic tier. Another 22 points would lift it into a rarer tier.
That score comes from 6 science badges — Variable star, Distant (over 1,000 light-years), Carbon star (sooty red), Deep red star, Strongly 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.
