Deimos, one of Mars' two moons, has a very thin atmosphere, primarily composed of carbon dioxide (CO2) and nitrogen (N2). Due to its low gravity and lack of significant geological activity, Deimos cannot retain a substantial atmosphere, and any gases present are likely to be transient. The moon's surface is also exposed to solar wind, which can interact with its regolith and contribute to the minimal atmospheric presence. Overall, Deimos' atmosphere is extremely tenuous compared to that of larger celestial bodies.
