50 Per is an uncommon variable star. It lies about 68.5 light-years from Earth, sits in the constellation Per, shines at apparent magnitude 5.52 and has spectral type F7V.
Its spectrum reads F7V — an F-type star — a little hotter, whiter and shorter-lived than the Sun.
Look for 50 Per in the constellation Per. At apparent magnitude 5.52, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, 50 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.
50 Per scores 23 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 11 points would lift it into a rarer tier.
That score comes from 6 science badges — Variable star, Naked-eye visible, Yellow-white F-type star, Main-sequence star, Barely variable (under 0.05 mag) and A named variable 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.
