TOI-1386 is a Sun-like G-type star (about 1.04 solar masses, 5,735 K, 1.02 solar radii), 147 light-years from Earth. TOI-1386 b is a 0.14-Jupiter-mass companion, with an orbital period of 25.8 days, at 0.173 AU from its star, and an equilibrium temperature near 615 K, discovered in 2024 via transit. TOI-1386 c is a 0.24-Jupiter-mass companion, with an orbital period of 232 days, at 0.750 AU from its star, on an eccentric orbit (e ≈ 0.38), discovered in 2024 via radial velocity. Mutual gravitational tugs between the planets can slowly reshape their orbits, preserving clues to the system's assembly.
