it is considered as an exosphere
No. The moons of Mars are far too small to have atmospheres.
Mars has two moons, Phobos and Deimos, both of which are small and have very thin atmospheres. Their atmospheres consist mostly of carbon dioxide, with trace amounts of other gases such as nitrogen and oxygen. These atmospheres are so tenuous that they do not offer any significant protection or support for any form of life.
Space does not have an atmosphere. It is generally considered a vacuum. Planets and some moons have atmospheres.
No, a planet's moons and atmosphere do not directly affect its gravity. Gravity is primarily determined by the mass of the planet itself; the more massive the planet, the stronger its gravitational pull. While moons can influence tidal forces and an atmosphere can affect pressure and weather, they do not change the fundamental gravitational force exerted by the planet.
An airless moon is a moon that does not have an atmosphere. Without an atmosphere, there is no air or weather on the moon's surface. Examples of airless moons in our solar system include Earth's moon and many of the moons of the outer planets.
Mercury has no moons and no atmosphere. Venus has an atmosphere but no moons. Mercury probably has no moons and no atmosphere because it is very close to the sun.
Titan is the only one of Saturn's moons that has an appreciable atmosphere. It is most like earth's atmosphere in its high concentration of nitrogen (98% compared to Earth's 78%).
The moon does not have an atmosphere.
There is no atmosphere on the moon. There is insufficient gravity to keep an atmosphere there.
No. The moons of Mars are far too small to have atmospheres.
Zero
Titan
The moon has no atmosphere. No air!
The planet Mars is the only planet known with two moons and a predominantly CO2 atmosphere.
Mars has two moons, Phobos and Deimos. Both moons have a very thin atmosphere, so they do not have traditional weather like what we experience on Earth. The surface temperatures on these moons can vary greatly depending on their position relative to Mars and the Sun.
PLUH
The Moon has very little atmosphere, and is barely measurable.
