The Moon has almost no atmosphere, so that is unable to influence lunar gravity - which is about one sixth of Earth's gravity.
The moon's gravity is too weak to hold on to an atmosphere.
Moon gravity is less because the atmosphere and mass and the earths gravity is greater than the moon if you weight yourself in the earth and then you weighted yourself in the moon you would weight less in the moon you could actually float in the moon because of its atmosphere and mass
moon's gravity is (1/6)th of the earth's gravity
Moon
That is related to the fact that the Moon has less gravity - its escape velocity is less. This allows any atmosphere to evaporate into space within a reasonable time.
There is no atmosphere on the Moon because it does not have sufficient gravity to hold an atmosphere to it's surface.
The moon is too small to created the gravity necessary to retain an atmosphere.
The moon's gravity is too weak to hold on to an atmosphere.
There is no atmosphere on the moon. There is insufficient gravity to keep an atmosphere there.
Moon gravity is less because the atmosphere and mass and the earths gravity is greater than the moon if you weight yourself in the earth and then you weighted yourself in the moon you would weight less in the moon you could actually float in the moon because of its atmosphere and mass
The moon has gravity, but it is much weaker than the gravity on Earth. It is not enough to hold onto an atmosphere.

That is related to the fact that the Moon has less gravity - its escape velocity is less. This allows any atmosphere to evaporate into space within a reasonable time.
The atmosphere we breath is held round the earth's surface due to earth's gravity. Without this gravity, earth's atmosphere would disperse into space. Because our moon's gravity is weak, so there is no atmosphere on the moon.
Where a planet or moon has an atmosphere, it is the gravity of the moon or planet that holds the atmosphere on the planet or moon.
The moon's gravity is not strong enough to support an atmosphere.
