The exosphere is a very thin atmosphere that surrounds the earth and is a place were the molecules of the gravitational bounds to the body of the planet as the concentration of gases at this layer is very low for them to remain as a gas and interact with each other.
The gases that can be found under this layer are the hydrogen and carbon dioxide. This upper part of the atmosphere has direct impacts for the solar radiation as this layer begins from a distance of 2,300,000 to 3,280,000 ft from the surface.
