HD 190360 is a Sun-like G-type star (about 1.00 solar masses, 5,560 K), 16.0 light-years from Earth. HD 190360 c is a 0.08-Jupiter-mass companion, with an orbital period of 17.1 days, at 0.130 AU from its star, on an eccentric orbit (e ≈ 0.16), discovered in 2005 via radial velocity. HD 190360 d is a 11.9-Earth-mass planet, with an orbital period of 88.7 days, at 0.389 AU from its star, on an eccentric orbit (e ≈ 0.06), discovered in 2026 via radial velocity. Mutual gravitational tugs between the planets can slowly reshape their orbits, preserving clues to the system's assembly.
