61 Virginis d (abbreviated 61 Vir d) is a proposed exoplanet orbiting the 5th apparent-magnitude G-type main-sequence star 61 Virginis in the constellation Virgo. 61 Virginis d would have a minimum mass of 22.9 times that of Earth and orbits nearly one-half the distance to the star as Earth orbits the Sun with an eccentricity of 0.35. This planet would most likely be a gas giant like Uranus and Neptune.
This planet was induced on 14 December 2009 from using a precise radial velocity method taken at Keck and Anglo-Australian Observatories. As of 2012 it has not been confirmed by other measurements such as from HARPS.
