HD 22204 is an uncommon star. It lies about 1,244.9 light-years from Earth, sits in the constellation Eri, shines at apparent magnitude 10.11 and has spectral type A7/A8II/III.
Its spectrum reads A7/A8II/III — an A-type star: white-hot, typically about twice the Sun's mass, and the class most of the sky's famous bright stars belong to.
Look for HD 22204 in the constellation Eri. At apparent magnitude 10.11, a small backyard telescope will bring it into view.
Like any astronomical target, HD 22204 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.
HD 22204 scores 26 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 8 points would lift it into a rarer tier.
That score comes from 4 science badges — Star, Distant (over 1,000 light-years), White A-type star and Bright giant — 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.
