You might have heard that Venus is that the hottest planet within the scheme. In fact, down at the surface of Venus it’s hot enough to melt lead. But why is Venus so hot?

Venus is so hot because it's surrounded by a awfully thick atmosphere which is about 100 times more massive than our atmosphere here on Earth. As sunlight passes through the atmosphere, it heats up the surface of Venus. Most of this heat cannot escape into space because it's blocked by the very thick atmosphere of Venus. the warmth becomes trapped and builds up to extremely high temperatures. This trapping of warmth by the atmosphere is named the  greenhouse effect because it's just like how the glass a greenhouse traps heat. The greenhouse effect on Venus causes the temperatures at its surface to succeed in 864 degrees Fahrenheit (462 degrees Celsius), making Venus hottest planet within the entire Solar System!
