Why is Mars so hot?
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.
