Venus is the planet closest to Earth's orbital path, and it is the second planet from the Sun. It's a rocky planet with a similar size, structure, and chemical composition to Earth. As a result, Venus is frequently referred to as Earth's twin. Venus, on the other hand, is very different from Earth. The planet is covered in thick sulfuric acid clouds and has an average surface temperature of 480 degrees Celsius (900 degrees Fahrenheit), making it the hottest planet in the solar system.
