    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.

    The planet HD 73534 b is named Drukyul. The name was selected by Bhutan as part of the NameExoWorlds campaigns during the 100th anniversary of the IAU. Drukyul ( འབྲུག་ཡུལ ) means "land of the thunder dragon", the native name of Bhutan. [3] [4]
