About how hot is Wasp-76b?
A
5000
B
3000
C
4000
D
2500
Explanation: 

Detailed explanation-1: -Its mass is 0.92 times that of Jupiter. WASP-76b was discovered on October 21, 2013 and is the only known planet in the WASP-76 system as of 2022. Wasp-76b equilibrium temperature is at 2, 190 K (1, 920 °C; 3, 480 °F), and its measured day-side temperature is hotter at 2, 500 ± 200 K (2, 227 ± 200 °C; 4, 040 ± 360 °F).

Detailed explanation-2: -It’s dubbed an “ultra-hot Jupiter” because it’s close to the star it orbits. As a “tidally locked” planet, one side of WASP-76b always faces the sun – so average temperatures range from 2, 400 degrees Fahrenheit on its permanent night half to 4, 400 degrees on its permanent day half.

Detailed explanation-3: -As a result, the upper atmosphere on the daytime side of WASP-121 b gets as hot as 5, 400 degrees Fahrenheit (3, 000 degrees Celsius).

Detailed explanation-4: -WASP-76 b is a gas giant exoplanet that orbits an F-type star. Its mass is 0.92 Jupiters, it takes 1.8 days to complete one orbit of its star, and is 0.033 AU from its star.

Detailed explanation-5: -WASP-76b transits the star, which means from our point of view on Earth it passes directly in front of the star, making a mini-eclipse. Because it’s a gas giant, its atmosphere gets thinner with height, allowing some starlight to pass through.
