WASP-75 is an F-type main-sequence star about 980 light-years away. The star is much younger than the Sun at approximately 2.9 billion years.^[6] WASP-75 is similar to the Sun in its concentration of heavy elements.^[5]

Planetary system

In 2013 a transiting hot Jupiter planet b was detected on a tight, circular orbit,^[8] and the planet was confirmed in 2018.^[5] Its equilibrium temperature is 1,688 K.^[5]
