HIP 17687 is an uncommon star. It lies about 1,598.8 light-years from Earth, sits in the constellation Cep, shines at apparent magnitude 10.12 and has spectral type B8.
Its spectrum reads B8 — 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 17687 in the constellation Cep. At apparent magnitude 10.12, a small backyard telescope will bring it into view.
Like any astronomical target, HIP 17687 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 17687 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 5 science badges — Star, Distant (over 1,000 light-years), Never sets (northern circumpolar), Hot blue B-type star and Blue-white 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.
