15. The atmosphere of the Moon is very tenuous

and insignificant in comparison with that of the Earth. One source of the lunar atmosphere is outgassing: the release of gases such as radon that originate from radioactive decay within the crust and mantle. Another important source is the bombardment of the lunar surface by micrometeorites, the solar wind, and sunlight, in a process known as sputtering.

Thanks to wikipedia :-)
