HD 45652 b is a gas giant planet orbiting at only 0.23 AU from the star, which takes 44 days to orbit. It has mass half that of Jupiter, but the inclination is not known. If inclination is known, then the true mass of this planet will be more massive. Also the radius of this planet is not known. This planet was discovered in May 2008 by ELODIE spectrograph.
