KOI-351 f is a rare exoplanet. It lies about 2,766.6 light-years from Earth, shines at apparent magnitude 13.88, has an equilibrium temperature near 407 K and spans roughly 2.88 Earth radii.
Too light to be solid rock and too heavy to be all gas: most likely a deep global ocean or a thick steamy envelope over a rocky core.
At apparent magnitude 13.88, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, KOI-351 f 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.
KOI-351 f scores 41 points on Spacedle's rarity scale, which places it in the rare tier. Another 9 points would lift it into a rarer tier.
That score comes from 6 science badges — Confirmed exoplanet, Distant (over 1,000 light-years), Sub-Neptune, Richly packed system, 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.
