why moon has no atmosphere

rishu54: Another reason is because the moon is relatively close to the sun. This reason is tied closely to the moon having weak gravity. The solar wind from the sun helps strip away a weakatmosphere. Earth and Venus do not suffer the same fate since the gravity is high enough to hold the atmospherein place.

because the value of escape velocity for moon is very small as compared to earth. the thermal velocity of the air molecules is enough large to escape the moons surface

Because moon is too small compared to earth ,the moon is about 1/4 the size. This reduce the amount of gravity. Strong gravity is needed to hold an atmosphere into place as with the weak gravity , gases that are emitted from the surface are quickly lost to outer space
