Host star.
Kepler-11c's host star, Kepler-11, is a G-type star 2,000 light-years away in the Cygnus constellation. With a mass of .95 M, a radius of 1.1 R, a metallicity of [Fe/H] = 0, and an effective temperature of 5680 (± 100) K,
Kepler-11c
Kepler-11c is an exoplanet discovered in the orbit of the Sun-like star Kepler-11 by the Kepler spacecraft, a NASA telescope aiming to discover Earth-like planets. It is the second planet from its star, and is most likely a water planet with a thin hydrogen–helium atmosphere. Kepler-11c orbits Kepler-11 every 10 days, and has an estimated density twice that of pure water. It is estimated to have a mass thirteen times that of Earth and a radius three times that of Earth.
