HD 73534 b
HD 73534 b is an extrasolar planet which orbits the G-type subgiant star HD 73534, located approximately 272 light years away in the constellation Cancer. It is at least 15% more massive than Jupiter and orbits at an average distance of 3.15 AU and takes 4.9 years to complete the orbit in a nearly circular path with an eccentricity similar to Jupiter.[1] This planet was detected by radial velocity method on August 12, 2009.
