The Coldest Planet And Hottest Planet In Our Solar System

As the planets in our Solar System get further away from the Sun, they generally get colder. So what is the coldest planet of our Solar System. That would be Neptune, the 8th and final planet in the Solar System. If Pluto was still a planet, it would be colder, but now it's Neptune.

It is the hottest planet in the solar system. So what makes Venus hotter than Mercury? Mercury doesn't have any atmosphere, and atmosphere can hold and trap heat. Any heat that Mercury receives from the sun is quickly lost back into space.
