61 Virginis is a star similar to the Sun, located about 27.8 light-years away in the constellation of Virgo.

There is some evidence that it may have a jovian planet, but seems not to have a nearby massive companion. [ [http://adsbit.harvard.edu/cgi-bin/nph-iarticle_query?bibcode=1988ApJ...331..902C Campbell et al, 1988] , pages 904, 906, and 919] A subsequent study also failed to find the large substellar companion (with 20 to 80 times the mass of Jupiter) or a Jupiter-class planet [ [http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=1999ApJ...526..890C&db_key=AST&high=38e0b7728721257 Cumming et al, 1999] ] , therefore it is a good candidate for possessing a family of terrestrial planets, with an orbit slightly less and a year slightly smaller than that of the Earth.
