About this world
Kepler-407 c is a gas giant orbiting Kepler-407, a yellow, Sun-like star (type G) 1.1 thousand light-years from Earth. It is about 1.1 times the size of Jupiter (its size estimated from its mass) and holds 13 Jupiter masses. It completes an orbit every 8.21 years at 3.3 AU from its star, on a strongly elongated orbit (e = 0.22).
Its equilibrium temperature is about 147 K (−126 °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 2014 by radial velocity with W. M. Keck Observatory. The star wobbles toward and away from us, Doppler-shifting its spectrum. Kepler-407 has 2 known planets; the others are Kepler-407 b.
