HR 6308 is an uncommon star. It lies about 540.9 light-years from Earth, sits in the constellation Oph, shines at apparent magnitude 5.88 and has spectral type M1/M2III.
Its spectrum reads M1/M2III — 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 HR 6308 in the constellation Oph. At apparent magnitude 5.88, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, HR 6308 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.
HR 6308 scores 30 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 4 points would lift it into a rarer tier.
That score comes from 5 science badges — Star, Naked-eye visible, 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.
