The Moon has no atmosphere for a number of reasons:
It is not dense or big enough to have a gravitic pull to retain anything.
It does not revolve, so it cannot hold on to anything like atmosphere.
It has never had one.
Mercury has no moon nor an atmosphere.
The moon is outside of the earth's atmosphere.
The Moon has a wider temperature range and it never has thunderstorms. Both of these things are because it has practically no atmosphere, so there is little to protect it from the Sun's heat and there are no winds and no clouds form to provide storms.
All of the planets except Mercury and Venus, which have no moons, have at least one moon that lacks an atmosphere.
The moon's gravity is too weak to hold on to an atmosphere.
The atmosphere of Earth's moon is so thin that it is practically non-existent. The atmospheric pressure at the surface is extremely low, and varies from day to night. In addition, the atmosphere contains no oxygen or nitrogen, which might help support life.
Because there is practically no atmosphere on the Moon and so there is no real weather like wind, rain etc. that causes weathering, like there is on Earth.
There's no atmosphere on the Moon.
The moon has no atmosphere.
No. The moon does not have an atmosphere.
The Moon has no atmosphere.
The moon has no atmosphere
There is no atmosphere on the Earth's moon.
The moon has no atmosphere and it is not within the Earth's atmosphere, so it never got "to the atmosphere."
Titan is the moon with atmosphere, it's the moon of Saturn
Practically, the moon is surrounded by space: there is virtually no atmosphere and thus no oxygen or water that we know of. Unless an enclosed colony was built with life-sustaining features, a visit to the moon, without protection of a space suit or such, would be fatal.
Jupiter's moon Io does not have an atmosphere. The only known moon to have an atmosphere is Saturn's moon Titan, which has a nitrogen-based atmosphere.
