HD 156098 is a Sun-like F-type star (about 1.29 solar masses, 6,419 K), 48.2 light-years from Earth. HD 156098 b is a 0.05-Jupiter-mass companion, with an orbital period of 21.9 days, at 0.167 AU from its star, on an eccentric orbit (e ≈ 0.11), discovered in 2022 via radial velocity. HD 156098 c is a 5.23-Jupiter-mass companion, with an orbital period of 21.5 years, at 8.415 AU from its star, on an eccentric orbit (e ≈ 0.39), discovered in 2022 via radial velocity. Mutual gravitational tugs between the planets can slowly reshape their orbits, preserving clues to the system's assembly.
