About this world
Kepler-150 f is a sub-Neptune orbiting Kepler-150, a yellow, Sun-like star 2.91 thousand light-years from Earth. It is about 3.6 times the size of Earth. It completes an orbit every 637 days at 1.2 AU from its star.
Its equilibrium temperature is about 228 K (−45 °C), which places it in the conservative habitable zone: the band where liquid water could exist on a rocky surface. At its size it almost certainly keeps a deep envelope of hydrogen and helium.
It was discovered in 2017 by transit with Kepler. A planet crosses its star and dims it by a tiny, periodic fraction. Kepler-150 has 5 known planets; the others are Kepler-150 b, Kepler-150 c, Kepler-150 d and Kepler-150 e.
