Triton retains an atmosphere primarily due to its significant gravitational pull and its geological activity, which can generate gases. Its relatively large size and low gravity allow it to hold onto lighter atmospheric components. In contrast, Phobos is much smaller and has a weaker gravitational field, making it unable to retain an atmosphere. Additionally, its proximity to Mars, where atmospheric interactions are more pronounced, further diminishes any potential for atmospheric retention.
Triton retains an atmosphere primarily due to its significant gravity and relatively low temperature, which allows it to hold onto gases like nitrogen. Its geologic activity, including geysers that release nitrogen and possibly other gases, also contributes to maintaining its atmosphere. In contrast, Phobos is much smaller and has insufficient gravity to retain an atmosphere, as its weak gravitational pull allows any gases to escape into space easily. Additionally, Phobos lacks significant geologic activity that could replenish any transient atmosphere it might have had.
Phobos has little if any atmosphere; like Mars, we would assume that if any oxygen was present, it could only be measured in parts per million.
Phobos, one of Mars' moons, does not have its own atmosphere or climate. It is too small to retain an atmosphere, so it does not experience weather or climate patterns like those on Earth or larger planetary bodies.
it is either zero or very, VERY near zero. A zero air pressure implies there is no atmosphere. Phobos is merely a captured asteroid, these objects are too small, not enough mass, to be capable of a large enough gravitational field to maintain an atmosphere.
The planet with two moons is Mars. The moons are called Phobos and Deimos.

Phobos, one of the moons of Mars, has an extremely thin atmosphere composed mainly of carbon dioxide (CO2) and some traces of other gases like nitrogen and argon. However, the atmosphere on Phobos is so sparse that it is considered essentially a vacuum.
Triton has a very tenuous atmosphere of nitrogen.
Phobos has an extremely thin atmosphere, known as an exosphere, consisting mainly of sodium and potassium atoms. This exosphere is so sparse that it does not behave like a traditional atmosphere and does not provide any significant atmospheric pressure.
No. Phobos is tiny, one of the moons of Mars. There isn't any atmosphere, so no rain.

Triton's atmosphere is made up of about 70% Nitrogen, (N2) 20% Methane (CH4) and roughly 10% Carbon Monoxide (CO).
of course not titan has a dense atmosphere as well
Because phobos has no atmosphere the temperature varies greatly from around -4C (25F) on the sunlit side to -112C (-70F) on the night side.
Neptune's moon Triton also has a nitrogen atmosphere, making it one of the few moons in the solar system known to have a substantial atmosphere. This atmosphere is primarily composed of nitrogen with trace amounts of methane and carbon monoxide.
