Introduction

What is the hottest planet in our solar system, and why is it so hot?

Venus is the hottest planet, with an average surface temperature of 900 degrees Fahrenheit or 481 degrees Celsius. It’s the second closest to the Sun, with only Mercury orbiting closer. Interestingly enough, the high temperatures on Venus are largely due to a greenhouse effect due to the very high levels of carbon dioxide (CO2) in its atmosphere.
