1. The very slight gravitational field experienced by a mass that is far removed from any other mass, as in intergalactic or interstellar space.
2. A condition, such as a free fall or orbital motion, in which acceleration of an object causes it to appear weightless even in the presence of a strong gravitational force.
3. A minute shift in the earth's gravitational field that can occur through geologic processes in a region, such as the movement of the earth's crust along fault lines.


(Astronautics) the very low apparent gravity experienced in a spacecraft in earth orbit


(ˈmaɪ kroʊˌgræv ɪ ti)

a condition, esp. in orbit, where the force of gravity is so weak that weightlessness results.
