HD 45652 b is a gas giant extrasolar planet orbiting at only 0.23 AU from the star HD 45652 with an orbital period of 44 days. It has mass at least half that of Jupiter. As it was detected using the radial velocity method its true mass is dependent on the inclination of its orbit; if it is low then the true mass will be larger. Also its radius is not known.
