HD 110813 scores 66 points on Spacedle's rarity scale, which places it in the epic tier. Another 12 points would lift it into a rarer tier.
That score comes from 7 science badges — Variable star, Distant (over 1,000 light-years), Never sets (northern circumpolar), S-type star (zirconium giant), Deep red star, Dramatic variable (over 2 magnitudes) 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.
