Subject: Various Moon Questions

Does the moon have any atmosphere or does it just radiate into space
if we were to populate the moon would we have a similar magnetic
field to protect us against Solar radiation. Is the Moons core
liquid metal as ours is. What would the effect of a comet hitting
the moon have on Earth and has any large Metors hit the moon this 
century like the one that hit Siberia in ?? 1907 ?? .

Would it create strange shock waves on Earth 

Does the moon have a constant distance from the Earth or is
it moving closer of further from th Earth. Just trying to get the
feel of how the tidal waters would be affected.
