47Lam Per is an uncommon star. It lies about 421.9 light-years from Earth, sits in the constellation Per, shines at apparent magnitude 4.25 and has spectral type A0IVn.
Its spectrum reads A0IVn — an A-type star: white-hot, typically about twice the Sun's mass, and the class most of the sky's famous bright stars belong to.
Look for 47Lam Per in the constellation Per. At apparent magnitude 4.25, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, 47Lam Per 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.
47Lam Per scores 26 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 8 points would lift it into a rarer tier.
That score comes from 5 science badges — Star, Naked-eye visible, White A-type star, Subgiant (leaving the main sequence) and Blue-white 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.
