About this world
KIC 5437945 b is a Neptune-like planet orbiting KIC 5437945, a yellow-white F-type star 4.16 thousand light-years from Earth. It is about 0.57 times the size of Jupiter. It completes an orbit every 441 days at 1.2 AU from its star.
Its equilibrium temperature is about 308 K (35 °C): too cold for liquid water on its surface. At its size it almost certainly keeps a deep envelope of hydrogen and helium.
It was discovered in 2015 by transit with Kepler. A planet crosses its star and dims it by a tiny, periodic fraction. KIC 5437945 has 2 known planets; the others are Kepler-460 c.
