Why is there no atmosphere around the moon?
Pretty simple: According to the leading theory, the moon was made when a huge rock collided with Earth. With all the changes going on then, the moon was pounded by radiation with its deformed atmosphere, causing it to be swept away. Although it might have had an atmosphere when it was young but spherical, the solar winds emitted by the sun were to strong for the moon’s little gravity. And, the moon doesn’t have hardly enough mass to have an atmosphere… those fierce solar winds and lack of a magnetosphere will wipe that atmosphere right off of it!
