HR 4163 is an epic variable star. It lies about 679.5 light-years from Earth, sits in the constellation Hya, shines at apparent magnitude 4.89 and has spectral type C.
Its spectrum reads C — a carbon star, wrapped in so much soot that its light is filtered to a deep ruby red.
Look for HR 4163 in the constellation Hya. At apparent magnitude 4.89, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, HR 4163 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 4163 scores 52 points on Spacedle's rarity scale, which places it in the epic tier. Another 26 points would lift it into a rarer tier.
That score comes from 6 science badges — Variable star, Naked-eye visible, Carbon star (sooty red), 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.
