Detailed explanation-1: -Mars is reddish color and some people might have guessed that Mars is the hottest planet in the solar system. But just because it’s red, doesn’t make it the hottest. Mercury is the planet that is closest to the sun and therefore gets more direct heat, but even it isn’t the hottest.
Detailed explanation-2: -In orbit, Mars is about 50 million miles farther away from the Sun than Earth. That means it gets a lot less light and heat to keep it warm. Mars also has a hard time holding onto the heat it does get. On Earth, much of the sun’s heat gets trapped in our atmosphere, which acts like a blanket to keep our planet warm.
Detailed explanation-3: -(But Mercury is not the hottest planet in the solar system. The hottest planet is Venus.) On its dark side, Mercury gets very cold because it has almost no atmosphere to hold in heat and keep the surface warm. The temperature can drop down to minus 300 degrees Fahrenheit.
Detailed explanation-4: -Even though Mercury is closer to the Sun, Venus is the hottest planet in our solar system. Its thick atmosphere is full of the greenhouse gas carbon dioxide, and it has clouds of sulfuric acid. The atmosphere traps heat, making it feel like a furnace on the surface.
Detailed explanation-5: -You might also be surprised to learn that the closest planet to the Sun, Mercury, can also be extremely cold. While the side of Mercury facing the Sun is more than 400℃, the side facing away from the Sun is nearly-200℃. The reason for this is that Mercury does not have any atmosphere, unlike Earth.
