Why (19388) 1998 DQ3 is a trash asteroid
(19388) 1998 DQ3 scores 6 points on Spacedle's rarity scale, which places it in the trash tier. Another 9 points would lift it into a rarer tier.
That score comes from 3 science badges — Asteroid, Catalogue designation only and Mars-crosser — 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.
