K2-18 b is an epic exoplanet. It lies about 124 light-years from Earth, shines at apparent magnitude 13.48, has spectral type M2.5 V and has an equilibrium temperature near 284 K.
Sits where it's neither too hot nor too cold — liquid water could exist on a surface here.
At apparent magnitude 13.48, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, K2-18 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.
K2-18 b scores 54 points on Spacedle's rarity scale, which places it in the epic tier. Another 24 points would lift it into a rarer tier.
That score comes from 5 science badges — Confirmed exoplanet, In the habitable zone, Sub-Neptune, 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.
