A survey of currently known extrasolar planets indicates that close to 20 % of their hosting stars are members of binary systems . While the majority of these binaries are wide ( i.e. , with separations between 250 and 6500 AU ) , the detection of Jovian-type planets in the three binaries of \gamma Cephei ( separation of 18.5 AU ) , GL 86 ( separation of 21 AU ) , and HD 41004 ( separation of 23 AU ) have brought to the forefront questions on the formation of giant planets and the possibility of the existence of smaller bodies in moderately close binary star systems . This paper discusses the late stage of the formation of habitable planets in binary systems that host Jovian-type bodies , and reviews the effects of the binary companion on the formation of Earth-like planets in the system ’ s habitable zone . The results of a large survey of the parameter-space of binary-planetary systems in search of regions where habitable planets can form and have long-term stable orbits are also presented .
