Kepler-539 is a Sun-like G-type star (about 1.05 solar masses, 5,820 K, 0.95 solar radii), 307 light-years from Earth. Kepler-539 b is a 0.97-Jupiter-mass companion, with an orbital period of 126 days, at 0.499 AU from its star, and an equilibrium temperature near 388 K, on an eccentric orbit (e ≈ 0.39), discovered in 2016 via transit. Kepler-539 c is a 2.40-Jupiter-mass companion, with an orbital period of 2.74 years, at 2.420 AU from its star, and an equilibrium temperature near 253 K, on an eccentric orbit (e ≈ 0.50), discovered in 2016 via transit.
