The larger the object, the more 'space' is displaced, and thus, the greater the gravity. The Moon displaces less 'space' than the Earth, so the Moon has less gravity. The space station displaces very little space AND its' shape does not lend itself to taking advantage of the spacial displacement, so it doesn't result in very much gravity.
Stand in a swimming pool and hold a beach ball under the water: the pressure of the water on the ball is a simulation of gravity. Hold a tennis ball under the water: far less pressure, yes? Now, hold something with the exact same collective mass as the beach ball (lets say one of those 'noodle' things the kids play with) and you'll have far less pressure on it than on the beach ball. Why? It has the same mass as the beach ball, so why isn't there the same amount of pressure (gravity) on it? Because the 'shape' of it does not lend itself to take advantage of the gravitational pressure.
Gravity can, however, be simulated with inertia. If the ship spins... centripical force and all that.
By spinning, the centripetal force creates artificial gravity on the space station.
The force of gravity keeps the space station in orbit as well as inertia that keeps the space station moving in a straight line.
I'm not sure if it's ever measured, but it could be approximated by calculating the surface gravity of a spherical asteroid of equal mass and dimensions.Assuming the mass of the International Space Station is 450 000 kg (M) and its mean radius is about 30 meters (r) , the surface gravity would be g = MG/r2 = about 0,00000003337 m/s2 (about 30 nanometers/square second).For comparison, Earth's surface gravity is about 9.81 m/s2, so the gravity you would experience standing on the surface of the International Space Station is about 0.3 millionth of a percent compared to earth. It's certainly too small a gravity to hold you attached to the station if you were standing on it.If you're inside the space station, in the center of the station, there is zero gravity because you are in the center of gravity because the mass of the station is situated around you.Panu, M.Sc.
If he is aboard something that's in Earth-orbit, like the International Space Station or the Space Shuttle, then Earth's gravity is what's keeping him in orbit.
Yes, there is gravity on the International Space Station (ISS), but it is not due to the station being in Earth's orbit. The sensation of weightlessness experienced by astronauts aboard the ISS is because they are in a state of constant free fall towards Earth, creating the effect of microgravity.

The International space station is constantly falling towards Earth under the pull of Earth's gravity (Just like any other object - gravity does not stop when you reach space!). However the Station is moving very fast horizontally and, as the Earth is a sphere, this means that as it falls its path takes it round the Earth in a circle - it is in "orbit". This means that if you are in the space station you are falling as fast as gravity can pull you and therefore you do not feel the pull of gravity, making you weightless.
no.
the distance
Compared to a planet a space station is tiny. While all objects with mass gave gravity, that of a space station is negligible, and certainly could not keep a moon in orbit.
Gravity.
As of 2010, artificial gravity technology has not been invented.
