HD 47536 b is an extrasolar planet located approximately 400 light-years away[1] in the constellation of Canis Major, orbiting the star HD 47536. The mass and semimajor axis are not exactly known, the mass can either be 4.96 or 9.67 MJ and semimajor axis can either be 1.61 or 2.25 AU, both depending on the mass of parent star. The orbital period about HD 47536 is 430 days or 1.18 years.
Its inclination and thereby true mass is being calculated via astrometry with Hubble. The astrometricians expect publication by mid-2009.[4]
