61 Virginis d (abbreviated 61 Vir d, also designated as HD 115617[1]) 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.[2][3] As of 2012 it has not been confirmed by other measurements such as from HARPS,[4] and in 2021 it was found to be a false positive.[5]: 75

61 Virginis d es un planeta extrasolar que orbita la estrella de tipo G 61 Virginis, localizado aproximadamente a 27 años luz en la constelación de Virgo. Este planeta tiene una masa 22,9 veces la de la Tierra y tarda 123 días en completar su periodo orbital, siendo su semieje mayor de aproximadamente 0,47 UA. Este planeta fue descubierto el 14 de diciembre de 2009 usando el método de la velocidad radial y el telescopio Keck.[1][2] Es probable que sea un gigante gaseoso como Urano o Neptuno.Текст в блоке "Читать" взят с сайта "Википедия" и доступен по лицензии Creative Commons Attribution-ShareAlike; в отдельных случаях могут действовать дополнительные условия.
