HR 38 is a rare variable star. It lies about 1,812 light-years from Earth, sits in the constellation And, shines at apparent magnitude 6.71 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 HR 38 in the constellation And. At apparent magnitude 6.71, it is an easy target for binoculars.
Like any astronomical target, HR 38 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 38 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, Distant (over 1,000 light-years), Hot blue B-type star, Main-sequence star, Blue-white star, Intrinsically luminous (Mv < −2), 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.
