Kepler-111 is a Sun-like G-type star (about 1.12 solar masses, 5,914 K, 1.15 solar radii), 657 light-years from Earth. Kepler-111 b is a planet with 1.6 Earth radii, with an orbital period of 3.3 days, at 0.046 AU from its star, discovered in 2014 via transit. Kepler-111 c is a 0.70-Jupiter-mass companion, with an orbital period of 225 days, at 0.751 AU from its star, and an equilibrium temperature near 352 K, on an eccentric orbit (e ≈ 0.18), discovered in 2014 via transit. Mutual gravitational tugs between the planets can slowly reshape their orbits, preserving clues to the system's assembly.
