Extrasolar planet orbiting HD 117207
HD 117207 b is an exoplanet orbiting at 3.77 astronomical units around HD 117207, taking about 7.14 years to complete its orbit. Its orbit has a low to moderate eccentricity. This planet was announced in January 2005 by Marcy at the Keck Observatory.[1] HD 117207 b has a minimum mass of 1.88 Jupiter masses,[3] and in 2023 its inclination and true mass were determined via astrometry.[2]
