Detailed explanation-1: -Mars’ atmosphere is over 100 times thinner than Earth’s and is primarily composed of carbon dioxide, nitrogen and argon gases.
Detailed explanation-2: -The highest atmospheric density on Mars is equal to the density found 35 km (22 mi) above the Earth’s surface and is ≈0.020 kg/m3. The atmosphere of Mars has been losing mass to space since the planet’s core slowed down, and the leakage of gases still continues today. The atmosphere of Mars is colder than Earth’s.
Detailed explanation-3: -The atmosphere on Mars is mostly made of carbon dioxide. It is also 100 times thinner than Earth’s atmosphere, so even if it did have a similar composition to the air here, humans would be unable to breathe it to survive.
Detailed explanation-4: -Of all the planets in the solar system, Mercury has the thinnest atmosphere, thinner than even Mars. Several components are constantly replenished by the solar wind blowing off of the nearby sun.
