SOLAR SYSTEM

Detailed explanation-1: -The air in the exosphere is extremely thin-in many ways it is almost the same as the airless void of outer space. The layer directly below the exosphere is the thermosphere; the boundary between the two is called the thermopause. The bottom of the exosphere is sometimes also referred to as the exobase.

Detailed explanation-2: -On Earth, this region is called the thermosphere because temperatures as high as 1000 K are reached in the outermost layer, or exosphere.

Detailed explanation-3: -The exosphere is the outermost layer of our atmosphere. “Exo” means outside and is the same prefix used to describe insects like grasshoppers that have a hard shell or “exoskeleton” on the outside of their body. The exosphere is the very edge of our atmosphere.

Detailed explanation-4: -Along with hydrogen various gases like carbon dioxide, oxygen, and helium are present in the exosphere.

Detailed explanation-5: -While the exosphere is the planet’s most distant layer of the atmosphere, it is also the planet’s first line of protection against the sun’s rays. It is the first layer to shield the Earth from meteors, asteroids, and cosmic rays.
