because moon has small density and shorter radius than earth. specially density is more important for calculation of Gravity.
there are some stars that have small radius but greater Gravity. why? because they have Larger density

Does the moon have a stronger magnetic field than the earth?
Venus does not have a magnetic field.
Why would an astronaut weigh less on the moon than earth?
The moon is considerably smaller than the Earth, both in diameter and in mass, and it therefore has a much weaker gravitational field. The weight of an astronaut on the moon is the result of the mass of the astronaut, which is not changed by going to the moon, and the gravitation field of the moon. A weaker gravitational field produces a lower weight.
Do you need a magnetic compass on the moon?
Because the moon has no magnetosphere - compasses are based on magnetic energy. == ==
Where is earths moon located?
earths moon is located basicly on the earths gravitational pull called the ionosphere which is the highest magnetic field of earth
Explain why the force of gravity is weaker on the Moon than it is on the Earth?
The Moon's mass is smaller than the Earth's mass, and so it has a weaker gravitational pull.
Why doesn't the moon have a magnetic field?
Venus does not have a magnetic field because its rotational period is very slow. This means that if its core had a liquid metal component, it would not be moving fast enough to generate a field.
What is the magnetic strength of moon?
The moon does not have a dipolar magnetic field and its external magnetic field is quite weak when compared to that of the Earth.
Does the moon have a stronger magnetic field than the earth?
Venus does not have a magnetic field.
How does the sun influence tide?
it doesn't. There is a tidal effect due to the sun, weaker than from the moon, but due to similar causes.
Is the moon a source of earth's magnetic field?
No. The source of earth's magnetic field is the molten inner core. The moon due to its proximity of course influences our magnetic field but it is to be considered a "weak effect".
Who determined the source of the earth's magnetic field?
The moon
If magnetic compass does not work on moon Why electric motor work on moon?
No because the Moon does not have a magnetic field like the Earth does. The Earth's magnetic field appears to be created by a liquid metalic out core circulating around a solid core. This works like a dynamo which creates the magnetic field around the Earth. The Moon lacks a similar core stucture. This is also the reason why the Monn has no atmosphere.A magnetic compass would not work on the moon, for the moon does not have the magnetic field that the earth has, allowing us to use this device.No, because moon does not have magnetic force like earth

Why don't we see auroras on the moon?
The auroras we see on Earth are a result of Earth's magnetic field funneling high-energy particles from the sun into Earth's upper atmosphere, where excited electrons in gas molecules create a glow. The moon has no magnetic field and no atmosphere.
Do you need a magnetic compass on the moon?
Because the moon has no magnetosphere - compasses are based on magnetic energy. == ==
Why can you only see one side of the moon from the earths surface?
because of the earth and moon's magnetic field and gravitational pull
Is the moon's gravitational pull stronger or weaker then the earth's?
weaker, since the moon is smaller
