HR 3582 is a rare variable star. It lies about 673.9 light-years from Earth, sits in the constellation Car, shines at apparent magnitude 4.93 and has spectral type B2IV-V.
Its spectrum reads B2IV-V — a blue-white B-type star, with a surface tens of thousands of degrees hot and a life measured in tens of millions of years.
Look for HR 3582 in the constellation Car. At apparent magnitude 4.93, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, HR 3582 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 3582 scores 34 points on Spacedle's rarity scale, which places it in the rare tier. Another 16 points would lift it into a rarer tier.
That score comes from 7 science badges — Variable star, Naked-eye visible, Hot blue B-type star, Subgiant (leaving the main sequence), Blue-white star, Barely variable (under 0.05 mag) 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.
