In our solar system, there is no moon that has an atmosphere which resembles that of the Earth. Note that the oxygen content of the Earth's atmosphere is the result of photosynthesis performed by green plants, and there is no other place in the solar system that has green plants (or any other kind of life that has yet been discovered). It remains theoretically possible and perhaps even likely that there are planets and moons elsewhere in the galaxy which have atmospheres resembling that of the Earth, but they have not actually been detected, and considering the great distances involved, perhaps they never will be.
Mars' moons have no atmosphere
it is considered as an exosphere

-- Mercury -- moon of Earth -- moons of Mars -- majority of moons of Jupiter and Saturn Note: While Mars technically has an atmosphere, its density is only around 1% of the density of earth's atmosphere, so Mars is very close to joining the list.
They are both inner planets,have moons,and have an atmosphere
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%).
Mars' moons have no atmosphere
Venus is the same size as Earth and has no moons and has a thick atmosphere of mostly carbon dioxide.
All moons are denser that earths atmosphere
it is considered as an exosphere
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.
The planet that is half the size of the earth, has 2 moons, and has an atmosphere of mostly carbon dioxide is Mars. The average length of a day on Mars is 37 minutes longer than that of the Earth.

Mars has two moons: Phobos and Deimos. Both are tiny, asteroid-like bodies with no atmosphere and irregular surfaces. Both orbit much more closely to Mars than the moon orbits Earth.
