Because unlike Earth, the moon lacks an atmosphere. It also lacks an electromagnetic shield. Because of this any atmosphere on the moon would over time be blown away by solar winds. This doesn't happen to earth because our electromagnetic field generally protects us from solar winds.

Why do astronauts weigh less on the Moon than on the Earth?
Astronauts weigh less on the Moon than on Earth because the Moon has less mass and gravity than Earth. The gravitational force on the Moon is about 1/6th that of Earth, so objects (including astronauts) weigh less on the Moon due to this weaker gravity.
Why is a persons weight different on earth than on the moon?
The gravity is less on the Moon, because the Moon is smaller than earth; it has less mass, and therefore "sucks" less than the earth. Weight is gravity times mass, you have the same mass on Earth and on the Moon (and in space), but weigh less on the moon.
Why doesnt the moon have enough gravity on it to pull us down?
It does. Astronauts on the moon can jump higher than they do on Earth but they still come back down. The moon's gravity is weaker than Earth's because the moon has less mass.
Why is the gravitational force on moon less than that of that of earth?
The gravitational force on the Moon is less than that on Earth because the Moon has less mass than Earth. Gravity is directly proportional to mass, so the smaller mass of the Moon results in a weaker gravitational force.
Why do you weight less on the moon?
You weigh less on the moon compared to Earth because the moon has less mass and gravity. The gravitational pull on the moon is about 1/6th of that on Earth, so your weight appears to be lighter on the moon.
How come you would move differently on the earth than on the moon?
The mass of the moon is less than then the mass of the earth therefore the gravitational forces are less on the moon. It therefore allows people to take bigger strides or hops on the moon.
Why is there less or no gravity on the moon then there is on earth?
There is gravity on the moon. It is about on sixth what it is on Earth. This is because the moon has less mass than Earth does.
Why is the gravity on the moon less than on the earth?
because the moon has less mass then earth
Why is there no oxygen on the moon?
Because it's atmosphere is significantly weaker and much less dense than earth's. And also because there is no plant life to create oxygen.
Why do astronauts weigh less on the Moon than on the Earth?
Astronauts weigh less on the Moon than on Earth because the Moon has less mass and gravity than Earth. The gravitational force on the Moon is about 1/6th that of Earth, so objects (including astronauts) weigh less on the Moon due to this weaker gravity.
Why is a persons weight different on earth than on the moon?
The gravity is less on the Moon, because the Moon is smaller than earth; it has less mass, and therefore "sucks" less than the earth. Weight is gravity times mass, you have the same mass on Earth and on the Moon (and in space), but weigh less on the moon.
Why do thing weigh less on the moon?
The moon has weaker gravity than Earth does.
What phase is the moon in when less and less of the side facing the earth is lighted?
The moon is in its waning phase when less and less of the side facing the earth is lighted. This phase occurs after the full moon and leads up to the new moon when the side facing the earth is completely dark.
What are some differences between the earth and moon?
The moon is smaller, uninhabited, and barren. The Moon does not have oxygen but the Earth does. No gravity on moon but the Earth does. No water, land, life, on the moon.
Why doesnt the moon have enough gravity on it to pull us down?
It does. Astronauts on the moon can jump higher than they do on Earth but they still come back down. The moon's gravity is weaker than Earth's because the moon has less mass.
How much less is the Moon's gravity than that of the earth's?
Since the Moon's gravity is 1/6 that of Earth, the Moon's gravity is 5/6 less than that of Earth.
Why is the gravitational force on moon less than that of that of earth?
The gravitational force on the Moon is less than that on Earth because the Moon has less mass than Earth. Gravity is directly proportional to mass, so the smaller mass of the Moon results in a weaker gravitational force.
