WASP-61 is a single F-type main-sequence star about 1560 light-years away. The star is likely younger than the Sun at approximately 3.8
_−0.9 billion years. WASP-61 is depleted in heavy elements, having just 40% of the solar abundance of iron.

Planetary system

In 2012 a transiting superjovian planet b was detected on a tight, circular orbit. Its equilibrium temperature is 1565±35 K.

The planetary orbit is well aligned with the equatorial plane of the star, misalignment equal to 4.0
_−18.4°.
