## Why is space so cold?

When the suns heat in the form of radiation falls on an object, the atoms that make up the object will start absorbing energy. Since there is no way to conduct heat, the temperature of the objects in the space will remain the same for a long time. Hot objects stay hot and cold things stay cold.

## Do you freeze in space?
