HD 32518 b is an extrasolar planet which orbits the K-type giant star HD 32518, located approximately 383 light years away in the constellation Camelopardalis. It has a minimum mass three times greater than Jupiter and orbits the intermediate-mass giant star at a distance of only 0.59 AU in a very circular orbit. The orbit takes 10.35 months to complete one round trip around the star.[2] This planet was detected by the radial velocity method on August 12, 2009.
