HD 113337 is a Sun-like F-type star (about 1.41 solar masses, 6,774 K), 36.2 light-years from Earth. HD 113337 b is a 3.26-Jupiter-mass companion, with an orbital period of 318 days, at 1.022 AU from its star, on an eccentric orbit (e ≈ 0.28), discovered in 2013 via radial velocity. HD 113337 c is a 19.8-Jupiter-mass companion, with an orbital period of 14.9 years, at 6.805 AU from its star, on an eccentric orbit (e ≈ 0.16), discovered in 2020 via radial velocity. Mutual gravitational tugs between the planets can slowly reshape their orbits, preserving clues to the system's assembly.
