The atmosphere is composed of approximatly 79% Nitrogen - 20% Oxygen - 1% Argon and 'other gasses'
The exosphere contains low densities of hydrogen, helium, and traces of other gases such as oxygen and carbon dioxide. These gases are present at extremely low concentrations due to the high altitude of the exosphere.

Some common atmospheric names include troposphere, stratosphere, mesosphere, thermosphere, and exosphere. These layers make up different levels of Earth's atmosphere based on factors like temperature and composition.

Mercury has no atmosphere, however, there is a trace exosphere containing hydrogen, helium, and oxygen, that gets dynamically created and destroyed.

The gases that make up Uranus' atmosphere is mainly hydrogen, helium, and methane.
The exosphere is a layer of the earth's atmosphere approximately 375 miles (600km) from the earth's surface.
