This is a list of all the stars within 55 light years that match ALL of the selection criteria for planets capable of supporting intelligent terrestrial type life forms within acceptable limits. There may be habitable planets around other stars not listed here, but the odds are very low.

This table lists all known stars within a radius of 54 light-years that are single or part of a wide multiple star system. They have no known irregularities or variabilities and are between 0.4 and 2.0 times the luminosity of the sun. Thus, a planet basically identical to Earth could be orbiting around any one of them. (Data from the Catalog of Nearby Stars, 1969 edition, by Wilhelm Gliese.)
