HD 17505 is a rare star. It lies about 2,861 light-years from Earth, sits in the constellation Cas, shines at apparent magnitude 7.14 and has spectral type O6e.
Its spectrum reads O6e — an O-type star — the hottest, rarest main class there is. Fewer than one star in a million is an O, and none of them lasts long.
Look for HD 17505 in the constellation Cas. At apparent magnitude 7.14, it is an easy target for binoculars.
Like any astronomical target, HD 17505 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.
HD 17505 scores 49 points on Spacedle's rarity scale, which places it in the rare tier. Another 1 point 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), Blazing O-type star and Intrinsically luminous (Mv < −2) — 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.
