TOI-2267 A is a cool M-dwarf (about 0.17 solar masses, 3,030 K, 0.21 solar radii). TOI-2267 b is a planet with 1.0 Earth radii, with an orbital period of 2.3 days, at 0.021 AU from its star, and an equilibrium temperature near 424 K, discovered in 2025 via transit. TOI-2267 c is a planet with 1.1 Earth radii, with an orbital period of 3.5 days, at 0.026 AU from its star, and an equilibrium temperature near 374 K, discovered in 2025 via transit. Mutual gravitational tugs between the planets can slowly reshape their orbits, preserving clues to the system's assembly.
