HD 31798 is an epic variable star. It lies about 2,912.1 light-years from Earth, sits in the constellation Ori, shines at apparent magnitude 10.24 and has spectral type C0ev.
Its spectrum reads C0ev — a carbon star, wrapped in so much soot that its light is filtered to a deep ruby red.
Look for HD 31798 in the constellation Ori. At apparent magnitude 10.24, a small backyard telescope will bring it into view.
Like any astronomical target, HD 31798 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 31798 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 7 science badges — Variable star, Distant (over 1,000 light-years), In Orion's hunting ground, Carbon star (sooty red), Deep red star, Dramatic variable (over 2 magnitudes) 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.
