HIP 67522 is a Sun-like G-type star (about 1.22 solar masses, 5,675 K, 1.38 solar radii), 127 light-years from Earth. HIP 67522 b is a Jupiter-sized planet around a star only about 17 million years old, young enough that flares and the planet still interact. HIP 67522 b is a planet with 10.0 Earth radii, with an orbital period of 7.0 days, at 0.075 AU from its star, and an equilibrium temperature near 1,175 K, on an eccentric orbit (e ≈ 0.06), discovered in 2020 via transit. HIP 67522 c is a planet with 7.9 Earth radii, with an orbital period of 14.3 days, at 0.123 AU from its star, and an equilibrium temperature near 917 K, on an eccentric orbit (e ≈ 0.08), discovered in 2024 via transit.
