HD 105618 is a Sun-like G-type star (about 1.01 solar masses, 5,671 K), 70.1 light-years from Earth. HD 105618 b is a 0.08-Jupiter-mass companion, with an orbital period of 10.0 days, at 0.091 AU from its star, on an eccentric orbit (e ≈ 0.46), discovered in 2022 via radial velocity. HD 105618 c is a 26.5-Jupiter-mass companion, with an orbital period of 211 years, at 35.7 AU from its star, on an eccentric orbit (e ≈ 0.13), discovered in 2022 via radial velocity. Mutual gravitational tugs between the planets can slowly reshape their orbits, preserving clues to the system's assembly.
