SOLAR SYSTEM

Detailed explanation-1: -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. It’s so hot on Venus, the metal lead would melt.

Detailed explanation-2: -(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-3: -Mercury’s surface temperatures are both extremely hot and cold. Because the planet is so close to the Sun, day temperatures can reach highs of 800°F (430°C). Without an atmosphere to retain that heat at night, temperatures can dip as low as-290°F (-180°C).

Detailed explanation-4: -Venus is so bright because it is covered by clouds that reflect much of the incoming sunlight. The yellowish clouds are made of sulphur and sulphuric acid.

Detailed explanation-5: -2. Mercury: The average temperature of Mercury is 167 degree Celsius. It is the first nearest planet from the Sun and the second hottest planet in the solar system.
