HIP 7238 is an uncommon variable star. It sits in the constellation Cas, shines at apparent magnitude 11.25 and has spectral type B2V.
Its spectrum reads B2V — a blue-white B-type star, with a surface tens of thousands of degrees hot and a life measured in tens of millions of years.
Look for HIP 7238 in the constellation Cas. At apparent magnitude 11.25, a small backyard telescope will bring it into view.
Like any astronomical target, HIP 7238 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.
HIP 7238 scores 24 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 10 points would lift it into a rarer tier.
That score comes from 6 science badges — Variable star, Never sets (northern circumpolar), Hot blue B-type star, Main-sequence 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.
