More than 150 moons inhabit our solar system, but Titan stands out as the only one with a dense atmosphere.
The layers of gases enveloping a planet or other celestial body form an atmosphere. About 78% of the atmosphere on Earth is made up of nitrogen, 21% of it of oxygen, and 1% of other gases.
Diatomic nitrogen (N2) makes up 78.8% of the Earth's atmosphere, followed by diatomic oxygen (O2), 20.5%, argon (A), 0.93 percent, water (H20), ranging from 0% to 4%, and carbon dioxide (CO2), 0.4%.
It not only has the oxygen we require to survive, but it also shields us from dangerous ultraviolet solar radiation. It generates the pressure necessary for liquid water to exist on the surface of our planet. Additionally, it warms our planet and maintains conditions that allow life to exist on Earth.
