HD 108874 c is a gas giant discovered in 2005[1] which orbits beyond the star's habitable zone, and receives insolation 15.9% that of Earth. It has minimum mass similar to Jupiter, although since inclination of the orbit is not known. The true mass of this planet will probably be much greater. This planet is believed to be a Water Cloud Jovian. The planets appearance is white water ice clouds. The planet is positioned at earthlike temperatures at mean orbital distance of 2.68 + 0.25 AU within habitability zone.
