The Catalog of Nearby Habitable Systems (HabCat) contains a selection of 17,129 candidate host stars for potential habitable exoplanets for complex life. It was created from a database of 118,218 stars in the Hipparcos Catalogue by combining the information on stellar distances, variability, multiplicity, kinematics and spectral classification (Table 1). The catalog was created on 2003 by scientists Jill Tarter and Margaret Turnbull under the auspices of Project Phoenix (1998-2004) as part of SETI.
This page is hosting HabCat together with some more recent analysis and visualizations. HabCat original publication listed 55 stars with planets on 2003. We also update this lists as part of our Habitable Exoplanets Catalog (HEC). There are now 165 stars with planets in the HabCat list. Note that this list is based on more recent stellar data and does not necessarily matches the original HabCat criteria. The list of all these stars with planets is listed here.
