Kepler-438 b is an epic exoplanet. It lies about 639.1 light-years from Earth, shines at apparent magnitude 15.1, has an equilibrium temperature near 288 K and spans roughly 1.12 Earth radii.
Sits where it's neither too hot nor too cold — liquid water could exist on a surface here.
At apparent magnitude 15.1, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, Kepler-438 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.
Kepler-438 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 4 science badges — Confirmed exoplanet, In the habitable zone, Earth-sized and Found by Kepler — 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.
