Why J1900+0405g is an uncommon pulsar
J1900+0405g scores 30 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 3 points would lift it into a rarer tier.
That score comes from 2 science badges — Pulsar and Deeply embedded (high DM) — 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.
