HD 73534 is

light years based on parallax measurements,[1] and it is drifting further away with a heliocentric radial velocity of +10 km/s.[4]

The star HD 73534 has the proper name Gakyid. The name was selected by Bhutan during the 100th anniversary of the IAU as part of the IAU's NameExoWorlds project. Gakyid means happiness. The planet HD 73534 b is named Drukyul, which means 'land of the thunder dragon', the native name for Bhutan.[7][8]

This is a

rotation period of around 53 days.[2]

In August 2009, it was announced that an exoplanet had been discovered using Doppler spectroscopy.[2] It is the first planetary system discovered in Cancer since that of 55 Cancri in April 1996, and the sixth planet, as 55 Cancri has five known planets.[citation needed]
