Why (5510) 1988 RF7 is a trash asteroid
(5510) 1988 RF7 scores 10 points on Spacedle's rarity scale, which places it in the trash tier. Another 5 points would lift it into a rarer tier.
That score comes from 4 science badges — Asteroid, Catalogue designation only, Mars-crosser and Stony asteroid — 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.
