Abstract: One of the most surprising discoveries of extrasolar planets is the detectionof planets in moderately close binary star systems. The Jovian-type planets inthe two binaries of Gamma Cephei and GJ 86 have brought to the forefrontquestions on the formation of giant planets and the possibility of theexistence of smaller bodies in such dynamically complex environments. Thediverse dynamical characteristics of these objects have made scientists wonderto what extent the current theories of planet formation can be applied tobinaries and multiple star systems. At present, the sensitivity of thedetection techniques does not allow routine discovery of Earth-sized bodies inbinary systems. However, with the advancement of new techniques, and with therecent launch of CoRoT and the launch of Kepler in late 2008, the detection ofmore planets possibly terrestrial-class objects in such systems is on thehorizon. Theoretical studies and numerical modeling of terrestrial andhabitable planet formation are, therefore, necessary to gain fundamentalinsights into the prospects for life in such systems and have great strategicimpact on NASA science and missions.
