What is the hottest planet?
In our Solar System:
Venus is the hottest planet. Its average surface temperature is
464 degrees Celsius (867 degrees Fahrenheit). Its atmosphere has
thick, pale, yellow clouds of carbon dioxide and sulfuric acid.
Carbon dioxide traps heat and prevents it from escaping to space.
The heating of the atmosphere produces strong winds of more than
300 kilometers per hour (186 mph) in the upper atmosphere. This is
also due to the dense atmosphere
mercury it is closest to the sun.
