HR 8223 is an uncommon variable star. It lies about 665.6 light-years from Earth, sits in the constellation Peg, shines at apparent magnitude 5.84 and has spectral type M4III.
Its spectrum reads M4III — 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 8223 in the constellation Peg. At apparent magnitude 5.84, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, HR 8223 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 8223 scores 31 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 3 points would lift it into a rarer tier.
That score comes from 6 science badges — Variable star, Naked-eye visible, Cool red M-type star, Giant star, Gently variable 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.
