HR 2591 is an epic variable star. It lies about 1,639 light-years from Earth, sits in the constellation Pup, shines at apparent magnitude 6.32 and has spectral type C3II.
Its spectrum reads C3II — a carbon star, wrapped in so much soot that its light is filtered to a deep ruby red.
Look for HR 2591 in the constellation Pup. At apparent magnitude 6.32, it is an easy target for binoculars.
Like any astronomical target, HR 2591 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 2591 scores 72 points on Spacedle's rarity scale, which places it in the epic tier. Another 6 points would lift it into a rarer tier.
That score comes from 8 science badges — Variable star, Distant (over 1,000 light-years), Carbon star (sooty red), Bright giant, Deep red star, Intrinsically luminous (Mv < −2), 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.
