WASP-75 is a F-type main-sequence star about 980 light-years away. The star is much younger than the Sun at approximately 2.9±0.2 billion years.^[5] WASP-75 is similar to the Sun in its concentration of heavy elements.^[3]

Planetary system

In 2013 a transiting hot Jupiter planet b was detected on a tight, circular orbit,^[6] and the planet was confirmed in 2018.^[3] Its equilibrium temperature is 1,688 K.^[3]
