WASP-76b is an exoplanet classified as a Hot Jupiter. It is located in the constellation Pisces and orbits its host star, WASP-76, at a distance of approximately 0.033 AU (4.9 million km; 3.1 million mi). Its orbital period is approximately 1.8 days, and its mass is about 0.92 times that of Jupiter.[4][5][6] The discovery of WASP-76b took place on October 21, 2013; as of 2022, it is the only known planet in the WASP-76 system. The equilibrium temperature of WASP-76b is estimated to be around 2,190 K (1,920 °C; 3,480 °F), However, the measured daytime temperature is higher, reaching approximately 2,500 ± 200 K (2,227 ± 200 °C; 4,040 ± 360 °F).[3]
