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]
