HD 108874 c is agas giant discovered in 2005 which orbits beyond the star'shabitable zone, and receivesinsolation 15.9% that ofEarth. It hasminimum mass similar toJupiter, although since theinclination of the orbit is not known thetrue mass of this planet could be much greater.The planet is possibly in a 4 : 1orbital resonance withHD 108874 b.[1]
