Venus, because of its atmosphere.

Explanation:

Venus has an average temperature of 462 degrees Celsius (864 degrees Fahrenheit) because it's atmosphere is much thicker than Earth, about 100 times more. That thick atmosphere traps heat from the sun like a blanket, letting it in but not letting it out. Venus is an example of a runaway greenhouse effect, called so because the effect is when air traps heat like a greenhouse.
