HD 203387 is an orange K-type dwarf (about 2.82 solar masses, 5,174 K), 61.7 light-years from Earth. HD 203387 b is a 3.48-Jupiter-mass companion, with an orbital period of 1.40 years, at 1.771 AU from its star, on an eccentric orbit (e ≈ 0.73), discovered in 2022 via radial velocity. HD 203387 c is a 7.49-Jupiter-mass companion, with an orbital period of 6.79 years, at 5.067 AU from its star, on an eccentric orbit (e ≈ 0.20), discovered in 2022 via radial velocity. Mutual gravitational tugs between the planets can slowly reshape their orbits, preserving clues to the system's assembly.
