HD 11964 b is an extrasolar planet, a gas giant like Jupiter approximately 110 light-years away in the constellationofCetus. The planet orbits the yellow subgiant star HD 11964 in a nearly-circular orbit, taking over 5 years to complete a revolution around the star at a distance of 3.34 astronomical units.[1]
The planet was discovered in 2005 and published as part of the Catalog of Nearby Exoplanets under the designation HD 11964 b.[2] However, since that time there has been confusion as to the designations of the planets in the HD 11964 system, leading to some sources designating this planet as "HD 11964 c".[3][4] In a recent review of the properties of multi-planet extrasolar planetary systems, the discovery team has stated that the correct designation for this planet is HD 11964 b.[1]
