HD 158186 scores 54 points on Spacedle's rarity scale, which places it in the epic tier. Another 24 points would lift it into a rarer tier.
That score comes from 9 science badges — Variable star, Distant (over 1,000 light-years), On the zodiac, Hot blue B-type star, Bright giant, Blue-white star, Intrinsically luminous (Mv < −2) and Gently variable — 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.
