HIP 31108 is an uncommon variable star. It lies about 689.5 light-years from Earth, sits in the constellation Gem, shines at apparent magnitude 10.43 and has spectral type N0.
Its spectrum reads N0 — a carbon star, wrapped in so much soot that its light is filtered to a deep ruby red.
Look for HIP 31108 in the constellation Gem. At apparent magnitude 10.43, a small backyard telescope will bring it into view.
Like any astronomical target, HIP 31108 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.
HIP 31108 scores 23 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 11 points would lift it into a rarer tier.
That score comes from 5 science badges — Variable star, On the zodiac, Deep red 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.
