Kepler-1399 b is an epic exoplanet. It lies about 4,519.5 light-years from Earth, shines at apparent magnitude 15.57, has an equilibrium temperature near 1,610 K and spans roughly 1.25 Earth radii.
Its surface is almost certainly an ocean of molten rock, kept liquid by the star it hugs.
At apparent magnitude 15.57, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, Kepler-1399 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-1399 b scores 58 points on Spacedle's rarity scale, which places it in the epic tier. Another 20 points would lift it into a rarer tier.
That score comes from 8 science badges — Confirmed exoplanet, Distant (over 1,000 light-years), Super-Earth, Lava world, Tidally locked, Blasted by starlight, Found by Kepler and Orbits a Sun-like star — 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.
