47Ome Ori is an epic variable star. It lies about 1,382 light-years from Earth, sits in the constellation Ori, shines at apparent magnitude 4.5 and has spectral type B3IIIe.
Its spectrum reads B3IIIe — 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 47Ome Ori in the constellation Ori. At apparent magnitude 4.5, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, 47Ome Ori 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.
47Ome Ori scores 59 points on Spacedle's rarity scale, which places it in the epic tier. Another 19 points would lift it into a rarer tier.
That score comes from 10 science badges — Variable star, Distant (over 1,000 light-years), Naked-eye visible, In Orion's hunting ground, Hot blue B-type star, Giant star, Blue-white star 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.
