Scientific paper

The Green Bank equation (1966) for the number of communicative civilizations, N, in our Galaxy is reconsidered in view of recent information on the multiplicity of solar-type stars and the possibilities of forming habitable planets around them. The results are contingent upon the statistical validity of Abt and Levy's (1976) work of stellar multiplicity and upon features of Heppenheimer's (1974) theory of planet formation in binary systems. It is concluded that N may have been overestimated by a factor of at least 50.
