HR 4074 is an epic variable star. It lies about 1,148.4 light-years from Earth, sits in the constellation Vel, shines at apparent magnitude 4.5 and has spectral type B3III.
Its spectrum reads B3III — 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 4074 in the constellation Vel. At apparent magnitude 4.5, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, HR 4074 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 4074 scores 51 points on Spacedle's rarity scale, which places it in the epic tier. Another 27 points would lift it into a rarer tier.
That score comes from 9 science badges — Variable star, Distant (over 1,000 light-years), Naked-eye visible, Hot blue B-type star, Giant star, Blue-white star, Intrinsically luminous (Mv < −2) and Barely variable (under 0.05 mag) — 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.
