WASP-67
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). WASP-67 is slightly depleted in heavy elements, having 85% of the solar abundance of iron.
