WASP-75b
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. WASP-75 is similar to the Sun in its concentration of heavy elements.

Planetary system

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