Gomeisa is a rare variable star. It lies about 161.7 light-years from Earth, sits in the constellation CMi, shines at apparent magnitude 2.89 and has spectral type B8Vvar.
Its spectrum reads B8Vvar — 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 Gomeisa in the constellation CMi. At apparent magnitude 2.89, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, Gomeisa 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.
Gomeisa scores 39 points on Spacedle's rarity scale, which places it in the rare tier. Another 11 points would lift it into a rarer tier.
That score comes from 8 science badges — Variable star, Naked-eye visible, Has a proper name, Hot blue B-type star, Main-sequence star, Blue-white star, Barely variable (under 0.05 mag) 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.
