48Sig Ori is an epic star. It lies about 1,072.9 light-years from Earth, sits in the constellation Ori, shines at apparent magnitude 3.77 and has spectral type O9.5V....
Its spectrum reads O9.5V... — an O-type star — the hottest, rarest main class there is. Fewer than one star in a million is an O, and none of them lasts long.
Look for 48Sig Ori in the constellation Ori. At apparent magnitude 3.77, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, 48Sig 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.
48Sig Ori scores 66 points on Spacedle's rarity scale, which places it in the epic tier. Another 12 points would lift it into a rarer tier.
That score comes from 8 science badges — Star, Distant (over 1,000 light-years), Naked-eye visible, In Orion's hunting ground, Blazing O-type star, Main-sequence 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.
