The hottest place in our solar system isn't a planet, but the surface of the Sun. It reaches a scorching temperature of around 5,500 degrees Celsius (9,932 degrees Fahrenheit).

However, if you're asking about the hottest planet, that title goes to Venus, with a surface temperature of around 464 degrees Celsius (867 degrees Fahrenheit). This extreme heat is due to a dense atmosphere of carbon dioxide that creates a runaway greenhouse effect.
