That score comes from 3 science badges — Star, Distant (>1000 ly) and Naked-eye visible — 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.
