Answer:Atmosphere
Explanation:
Moon is smaller in size than earth and hence, has very low force of gravity. Moon does not have atmosphere as its weaker force of gravity can not hold the atmosphere. Any present atmosphere on moon would have stripped away by strong solar wind. The weaker magnetic field of moon is one more reason for absence of atmosphere.
