WASP-67 is a K-type main-sequence star about 620 light-years away. The stars age is poorly constrained, but is likely older than the Sun`s at approximately 8.7+5.5
−8.6 billion years (ie. somewhere between 100 million years and the age of the universe).^[2] WASP-67 is slightly depleted in heavy elements, having 85% of the solar abundance of iron.^[3]

A multiplicity survey in 2016 has found one candidate stellar companion to WASP-67 at a projected separation of 4.422″±0.018″.^[6] Nonetheless, follow-up observations in 2017 failed to find any bound stellar companions.^[7]

Planetary system[edit]

In 2012 a transiting hot Jupiter planet b was detected on a tight, circular orbit.^[4] Its equilibrium temperature is 1050 K.^[8]

The planetary atmosphere contains water, and a cloud layer is located higher than in the similar gas giant HAT-P-38b, indicating a high planetary metallicity.^[8]
