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]

## Planetary system[edit]

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]
