3 Per is a common star. It lies about 244.7 light-years from Earth, sits in the constellation Per, shines at apparent magnitude 5.7 and has spectral type K0IV.
Its spectrum reads K0IV — a K-type star. Orange K dwarfs are the marathon runners of the galaxy, burning steadily for tens of billions of years.
Look for 3 Per in the constellation Per. At apparent magnitude 5.7, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, 3 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.
3 Per scores 19 points on Spacedle's rarity scale, which places it in the common tier. Another 3 points would lift it into a rarer tier.
That score comes from 4 science badges — Star, Naked-eye visible, Orange K-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.
