TOI-2141 is a Sun-like G-type star (about 0.90 solar masses, 5,635 K, 0.95 solar radii), 77.7 light-years from Earth. TOI-2141 c is a 6.1-Earth-mass planet, with an orbital period of 5.5 days, at 0.059 AU from its star, and an equilibrium temperature near 1,095 K, discovered in 2025 via radial velocity. TOI-2141 b is a 0.06-Jupiter-mass companion, with an orbital period of 18.3 days, at 0.132 AU from its star, and an equilibrium temperature near 728 K, discovered in 2023 via transit. Mutual gravitational tugs between the planets can slowly reshape their orbits, preserving clues to the system's assembly.
