HD 6718 is an 8th magnitude G-type main sequence star located approximately 179 light years away in the constellation Cetus. This star is slightly larger, cooler, brighter, and more massive than our Sun. Also its metal content is seven-eighths as much as the Sun. In 2009, a gas giant planet was found in orbit around the star.
