WASP-59 is a K-type main-sequence star about 379 light-years away. The star's age is essentially unconstrained by observations. WASP-59 is slightly depleted in heavy elements, having 70% of the solar abundance of iron. [2] The star produces extremely low levels of ultraviolet light, indicating an absence of flare activity. [4]
A multiplicity survey in 2015 did not detect any stellar companions to WASP-59. [5]
In 2012 a transiting hot Jupiter planet b was detected on a tight, mildly eccentric orbit. [6]
Its equilibrium temperature is 670±35 K. [6] The planet is unusually dense for a gas giant, representing an outlier on a mass-radius diagram. [7]
