TOI-201 is a Sun-like F-type star (about 1.32 solar masses, 6,423 K, 1.31 solar radii), 114 light-years from Earth. TOI-201 d is a 5.8-Earth-mass planet, with an orbital period of 5.8 days, at 0.070 AU from its star, on an eccentric orbit (e ≈ 0.30), discovered in 2026 via transit. TOI-201 b is a 0.52-Jupiter-mass companion, with an orbital period of 53.0 days, at 0.303 AU from its star, on an eccentric orbit (e ≈ 0.28), discovered in 2021 via transit. Mutual gravitational tugs between the planets can slowly reshape their orbits, preserving clues to the system's assembly.
