Why does Triton retains an atmosphere while Phobos does not?

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.


What is the atmosphere of Phobos?

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.


Are there any gases on the moon Phobos?

As far as we know, no.


Is there precipitation on Phobos?

No. Phobos is tiny, one of the moons of Mars. There isn't any atmosphere, so no rain.


Is there oxygen on the moon Phobos?

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.


What is Phobos climate?

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.


What is the atmospheric air pressure of Phobos?

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.


How hot is phobos?

Because phobos has no atmosphere the temperature varies greatly from around -4C (25F) on the sunlit side to -112C (-70F) on the night side.
