HD 108874 b is a gas giant announced in 2003.[1] The orbit lies in the star's habitable zone.[3] It is expected that any moons orbiting this planet are enriched in carbon, and are thus quite different from the silicate-rich bodies in the Solar System.[4] The planet is possibly in a 4 : 1 orbital resonance with HD 108874 c.[5]
