does the moon have its own gravity?
is there an altitude that i can reach and start feeling the gravity of the moon pulling me toward the moon?
If the moon have its own gravity is it of the same force as the gravity of the earth or is it lesser or greater?

yes of course the moon has gravity, otherwise it wouldn't orbit the Earth, but would crash into it. The moon's gravity is naturally, less than the Earth's or the Earth would be orbiting it instead. You need to go through space to get near enough to the moon, and there's no concept of altitude in space, so you can't get an answer to the last question

All Celestial bodies are mass structures. Mass structure are made up of micromass structures called atoms.So the smallest structure in the center of the moon is one atom. This poor little atom is surounded by a rain of other atoms which are pushed together unto it by a spacial phenomena called Gravity. Due to the Gravity phenomenon the moon has a whole volume of these atoms being held together into a volume of spherical shape.

Therefore the moon is a large mass volume being held to gether just like as any other celestial bodies in the Universe have their particular shape because of the Pressure of the substance of space which we call gravity.

So the more mass content is present in a celestial body the more Gravity Energy is required to hold it together in one piece.

Since the moon is smaller than the earth it would take less gravity energy to hold it together. However the smaller the mass the greater the gravity pressure. So it means that it is harder to contain a smaller mass into a particular volume than a larger mass.

So the Gravity process is basically a very vely simple process to understand. And this is the simplest explanation that can be given without abstact mathematics.

Everything with mass has gravity. The problem is that some things (the Earth, the Sun) have such a large gravitational pull that they overshadow others. There is a point at which you would start being pulled towards the moon. However, the moons size relation to the Earth means that point would be somewhere further than halfway between the Earth and moon (the moon has a smaller gravitational pull than the Earth because it is less massive (in the real sense of mass)).

Um... yeah... things that have mass have gravity. The more mass, the stronger the force of gravity. Using the Moon's gravity is how we've gotten to the Moon so far. The rocket is launched and gets the craft to the point where the Moon's gravity is stronger than the Earth's gravity and then the Moon pulls the craft toward it.

Yes, the moon does exert a gravitational pull on objects that have mass.

In fact, every object that has mass, including you, me and the big fat monkey, exert a gravitational pull on on objects that have mass.

However, the magnitude of the gravitational force exerted by an object on another object depends on its size. In this, case we are quite small compared to the moon or the earth, so the gravitational attraction between you and the big fat monkey is so small that we cannot feel it.

Back to your question. The moon is much smaller than the earth and thus, would exert a smaller gravitational pull than the earth on an object of the same mass.

And yes, there is an altitude, but is is very (heavy emphasis on the word 'very') high and it would take you 2-3 days to reach that altitude on a space shuttle (you can guess what i mean).

If you really want to know how gravity works, read Einstein's theory of general relativity ('Einstein for dummies' is a good start. You may have trouble deciphering the science lingo on the Internet)

The moon has a gravity of about 1 sixth that of the earth, ie if you weigh 60 kilos here you would weigh 10 kilos on the moon. The effect of the moon's gravity can be seen on earth through the tides in the sea - the sea is pulled up into a bulge almost twice a day by the moon passing overhead

the moon has it's own gravity, it's nearly 1/6 the strength of Earth's gravity ,,,
and yes, there's an altitude that u start feeling it's gravity, but it's v far from the earth, i mean , look at the earth's gravity, u should come closer to the earth till u reach the boundary of the atmosphere to start feeling it's gravity, sinse the moon is smaller than the earth, u should get closer to it to start feeling it's gravity,,
lesser than the earth's by 1/6 (as i mentioned above )

;)

Yes but not nearley enough as The Earth dose if i did not have gravity we would not be able to stand on it a good example showing that the Moon dose have gravity is When Apolo 13 launched things went great untill they got into space thats when everything wrong that could go wrong did long story short they used the moons gravity to catapult them back to earth

the moon has its own force of gravity like all the other bodies in space.

the force is much less than the force of gravity on earth because it's so much smaller- about 6 times less so thats why pics of landings on moon show the astronauts to be hovering.

You'll need to be in the gravitational field of the moon to feel its force.

Yes, everything that has mass has gravity. The larger an object is, the greater its gravitational pull is. That is why the planets go around the sun (which is the largest object in our solar system) and smaller objects such as moons revolve around their nearest planets.
