GJ 3323 is a cool M-dwarf (about 0.16 solar masses, 3,159 K, 0.12 solar radii), 5.4 light-years from Earth. GJ 3323 b is a 2.0-Earth-mass planet, with an orbital period of 5.4 days, at 0.033 AU from its star, on an eccentric orbit (e ≈ 0.23), discovered in 2017 via radial velocity. GJ 3323 c is a 2.3-Earth-mass planet, with an orbital period of 40.5 days, at 0.126 AU from its star, on an eccentric orbit (e ≈ 0.17), discovered in 2017 via radial velocity.
