61 Virginis c
61 Virginis c (abbreviated 61 Vir c) is an exoplanet orbiting the 5th apparent-magnitude G-type main-sequence star 61 Virginis in the constellation Virgo. 61 Virginis c has a minimum mass of 18.2 times that of Earth and orbits one-fifth the distance to the star as Earth orbits the Sun, at a precise distance of 0.2175 AU with an eccentricity of 0.14. This planet would most likely be a gas giant like Uranus and Neptune. This planet was discovered on 14 December 2009 from using a precise radial velocity method taken at Keck and Anglo-Australian Observatories.[1][2]
