TOI-199 is a Sun-like G-type star (about 0.94 solar masses, 5,255 K, 0.82 solar radii), 102 light-years from Earth. TOI-199 b is a 0.17-Jupiter-mass companion, with an orbital period of 105 days, at 0.425 AU from its star, on an eccentric orbit (e ≈ 0.09), discovered in 2023 via transit. TOI-199 c is a 0.28-Jupiter-mass companion, with an orbital period of 274 days, at 0.807 AU from its star, on an eccentric orbit (e ≈ 0.10), discovered in 2023 via transit. Mutual gravitational tugs between the planets can slowly reshape their orbits, preserving clues to the system's assembly.
