70 Virginis is a yellow dwarf star approximately 58 light-years away in the constellation Virgo. It is rather unusually bright for its spectral type and may be just starting to evolve into the subgiant phase.
In 1996, 70 Virginis was discovered to have an extrasolar planet in orbit around it.[2] There is also a dust disc at a temperature of 156 K located about 3.4 AU from the star.[3]
