15 Ori is an uncommon star. It lies about 538.2 light-years from Earth, sits in the constellation Ori, shines at apparent magnitude 4.81 and has spectral type F2IV.
Its spectrum reads F2IV — an F-type star — a little hotter, whiter and shorter-lived than the Sun.
Look for 15 Ori in the constellation Ori. At apparent magnitude 4.81, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, 15 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.
15 Ori scores 25 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 9 points would lift it into a rarer tier.
That score comes from 5 science badges — Star, Naked-eye visible, In Orion's hunting ground, Yellow-white F-type star and Subgiant (leaving the main sequence) — 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.
