Why J1902-5105 is an epic pulsar
J1902-5105 scores 54 points on Spacedle's rarity scale, which places it in the epic tier. Another 14 points would lift it into a rarer tier.
That score comes from 3 science badges — Pulsar, Millisecond pulsar and Binary pulsar — 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.
