The moon is considered to be surrounded by vacuum.
The tiny amount of gases near the moon is almost zero compared to the atmosphere of Earth - less than one hundred trillionth of Earth's atmospheric density at sea level.
One source of the lunar atmosphere is outgassing - the release of gases (e.g., radon and helium) that come from radioactive decay in the body of the moon.
Another source is the bombardment of the lunar surface by micrometeorites, the solar wind, and sunlight (a process known as sputtering).

Hydrogen protons from the solar wind
Any gases from volcanic out-gassing, which IS occasionally observed by amateur astronomers even today. A lot of that out-gassing will be H20 molecules.
The solar wind raises lunar regolith several meters for several hours because of its positive charge around lunar dawn.

i remember them saying the rocket exhaust from the landers on the apollo missions made up most of the moon's atmosphere. the natural atmosphere on the moon is extremely thin, nearly a perfect vacuum.

If you are referring to Earth's moon, it has no atmosphere, it's just vacuum.
-
It has no atmosphere.
-
It doesn't have one.

I'm not sure what it stands for, but I know it's H1N1
