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]
