HD 85390 b (also known as HIP 48235 b) is an extrasolar planet which orbits the G-type main sequence star HD 85390, located approximately 106 light years away[1] in the constellation Vela. This planet has at least one-seventh the mass of Jupiter and takes fifteen-sevenths years to orbit the star at a semimajor axis of 1.54 AU. The eccentricity of the planet is 0.41 ± 0.12, while its inclination is not known as the planet was discovered with the radial velocity technique. This planet was announced by the Swiss-led HARPS team on October 19, 2009, together with 29 other planets.
