HR 3183 is an epic star. It lies about 1,545.8 light-years from Earth, sits in the constellation Pup, shines at apparent magnitude 5.33 and has spectral type A3Ib/II.
Its spectrum reads A3Ib/II — an A-type star: white-hot, typically about twice the Sun's mass, and the class most of the sky's famous bright stars belong to.
Look for HR 3183 in the constellation Pup. At apparent magnitude 5.33, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, HR 3183 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 3183 scores 50 points on Spacedle's rarity scale, which places it in the epic tier. Another 28 points would lift it into a rarer tier.
That score comes from 6 science badges — Star, Distant (over 1,000 light-years), Naked-eye visible, White A-type star, Supergiant and Intrinsically luminous (Mv < −2) — 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.
