37 Geminorum is a star located at the northwest part of the constellation Gemini. Its distance from our Sun is about 56.3 light years. It is a solitary, yellow-white main sequence dwarf. It is unknown at the moment whether it has planets.
37 Geminorum has many physical properties in common with the Sun and is one of the nearest solar twins. Due to this fact some scientists believe that the prospects for life in its vicinity are good. In September, 2003, 37 Geminorum was identified by astrobiologist Margaret Turnbull from the University of Arizona in Tucson as one of the most promising nearby candidates for hosting life based on her analysis of the HabCat list of stars.
