Question

Why moon does not have any atmosphere as earth has

Answer 1

recent studies confirm that our moon does indeed have an atmosphere consisting of some unusual gases, including sodium and potassium, which are not found in the atmospheres of Earth, Mars or Venus.

Answer 2

Answer:

Reasons for which moon has no atmosphere:-)

As the value of gravity is very very small at the moon due to which escape velocity of moon is also too small.

Also thermal velocities are greater than escape velocity at the surface of the Moon due to which molecules can easily escape in the form of gases .

Sue to low Gravity, greater thermal velocity, smaller escape velocity moon has no atmosphere .
