'''WASP-75''' is a [[Astronomy:F-type main-sequence star|F-type main-sequence star]] about 980 light-years away. The star is much younger than the Sun at approximately {{val|2.9|0.2|u=billion years}}.<ref name=Bonfanti2015/> WASP-75 is similar to the Sun in its concentration of heavy elements.<ref name=Clark2018/>
