GJ 317 b is an uncommon exoplanet. It lies about 49.6 light-years from Earth, shines at apparent magnitude 12.4, has spectral type M3.5 V and has an equilibrium temperature near 100 K.
A deep-frozen world, too far from its star's warmth for anything to stay liquid.
At apparent magnitude 12.4, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, GJ 317 b is best seen from a dark site away from city lights, and when it is above the horizon depends on your latitude and the time of year. The visibility panel above works out tonight's viewing window for your saved location.
GJ 317 b scores 31 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 5 science badges — Confirmed exoplanet, Gas giant, Frozen world, Multi-planet system and Orbits a red dwarf — 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.
