NGC 2109 scores 7 points on Spacedle's rarity scale, which places it in the trash tier. Another 8 points would lift it into a rarer tier.
That score comes from 1 science badge — Star cluster — 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.
