Kepler-391 is an orange K-type dwarf (about 1.27 solar masses, 5,038 K, 2.88 solar radii), 869 light-years from Earth. Kepler-391 b is a 3.46-Jupiter-mass companion, with an orbital period of 7.4 days, at 0.083 AU from its star, and an equilibrium temperature near 930 K, on an eccentric orbit (e ≈ 0.46), discovered in 2014 via transit. Kepler-391 c is a 1.42-Jupiter-mass companion, with an orbital period of 20.5 days, at 0.164 AU from its star, and an equilibrium temperature near 662 K, on an eccentric orbit (e ≈ 0.27), discovered in 2014 via transit.
