HR 5644 is a rare variable star. It lies about 1,173.2 light-years from Earth, sits in the constellation TrA, shines at apparent magnitude 5.75 and has spectral type N0v.
Its spectrum reads N0v — a carbon star, wrapped in so much soot that its light is filtered to a deep ruby red.
Look for HR 5644 in the constellation TrA. At apparent magnitude 5.75, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, HR 5644 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 5644 scores 44 points on Spacedle's rarity scale, which places it in the rare 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), Naked-eye visible, 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.
