TOI-2345 is an orange K-type dwarf (about 0.73 solar masses, 4,687 K, 0.73 solar radii), 81.7 light-years from Earth. TOI-2345 b is a 3.5-Earth-mass planet, with an orbital period of 1.1 days, at 0.017 AU from its star, and an equilibrium temperature near 1,478 K, discovered in 2025 via transit. TOI-2345 c is a 7.3-Earth-mass planet, with an orbital period of 21.1 days, at 0.126 AU from its star, and an equilibrium temperature near 544 K, discovered in 2025 via transit. Mutual gravitational tugs between the planets can slowly reshape their orbits, preserving clues to the system's assembly.
