WASP-59 is a K-type main-sequence star about 379 light-years away in the constellation Pegasus. 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. The star produces extremely low levels of ultraviolet light, indicating an absence of flare activity. A multiplicity survey in 2015 did not detect any stellar companions to WASP-59.
Planetary system In 2012 a transiting hot Jupiter planet, WASP-59b, was detected on a tight, mildly eccentric orbit. Its equilibrium temperature is 670±35 K. The planet is unusually dense for a gas giant, representing an outlier on the mass-radius diagram.
