WASP-67 is a K-type main-sequence star about 620 light-years away in the constellation Sagittarius. The star's age is poorly constrained.[8] WASP-67 is slightly depleted in heavy elements, having 85% of the solar abundance of iron.[5]

A multiplicity survey in 2016 found one candidate stellar companion to WASP-67 at a projected separation of 4.422″±0.018″.[9] Nonetheless, follow-up observations in 2017 failed to find any bound stellar companions.[10]

## Planetary system

[edit]

In 2012 a transiting hot Jupiter planet, WASP-67b, was detected on a tight, circular orbit.[7] Its equilibrium temperature is 1050 K.[11]

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.[11]
