HIP 90225 is an uncommon variable star. It sits in the constellation Sct, shines at apparent magnitude 9.93 and has spectral type B3n + B0.
Its spectrum reads B3n + B0 — 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 90225 in the constellation Sct. At apparent magnitude 9.93, a small backyard telescope will bring it into view.
Like any astronomical target, HIP 90225 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 90225 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 4 science badges — Variable star, Hot blue B-type star, Strongly 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.
