Actually the number stated is only an approximate number. The exact value depends on where you are on the earth and even where the sun and moon are in relation to you. Astronauts above the earth experience microgravity and as a space probe moves away from the earth, the acceleration of gravity decreases.

Even on the surface of the earth, the acceleration due to gravity varies - depending on the density of the material underneath.
