mercury
the moon flys away from the earth

to move your body in motions
Your question is very nearly meaningless, because "in space" is not a well defined location and different locations and motions in space would have different properties. In freefall, which is what I suspect you meant, objects have no "weight" per se, but they still have inertia. It would therefore be possible to move objects you could not move on Earth, but it would not necessarily be easy, and if the object was already moving it could be difficult to stop it.
they are pulled by the Earths gravity
