TOI-771 is a cool M-dwarf (about 0.22 solar masses, 3,370 K, 0.23 solar radii), 25.3 light-years from Earth. TOI-771 b is a 2.5-Earth-mass planet, with an orbital period of 2.3 days, at 0.021 AU from its star, and an equilibrium temperature near 543 K, on an eccentric orbit (e ≈ 0.06), discovered in 2024 via transit. TOI-771 c is a 2.9-Earth-mass planet, with an orbital period of 7.6 days, at 0.046 AU from its star, and an equilibrium temperature near 365 K, on an eccentric orbit (e ≈ 0.07), discovered in 2025 via radial velocity.
