Yed Prior is a rare star. It lies about 171.1 light-years from Earth, sits in the constellation Oph, shines at apparent magnitude 2.73 and has spectral type M1III.
Its spectrum reads M1III — an M-type red star — and M stars are the silent majority: roughly three of every four stars in the galaxy are one.
Look for Yed Prior in the constellation Oph. At apparent magnitude 2.73, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, Yed Prior 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.
Yed Prior scores 38 points on Spacedle's rarity scale, which places it in the rare tier. Another 12 points would lift it into a rarer tier.
That score comes from 6 science badges — Star, Naked-eye visible, Has a proper name, Cool red M-type star, Giant star and Deep red 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.
