how much potential energy is accrued the further a body moves away from the earth?

obligatory excuse my ignorance. 

if an object at rest on earth is lifted to a higher altitude then the kinetic energy required to do so is converted to potential energy? 

so is there a limit to this?

&#x200B;

If an object is lifted higher and higher until it is only negligibly affected by the earth's gravitational field, does the amount of potential energy it gain keep increasing too? 

&#x200B;

Would the voyager probe or some equivalent far off former piece of earth have enormous potential energy?

Neatly this is how escape velocity is found. The kinetic energy of an object at escape velocity at sea level (or any other altitude you define escape velocity from) is equal to the amount of GPE it needs to gain to get out of the Earth's gravity well, basically to reach infinite distance at zero velocity.

Note that both KE and GPE have a mass term, which is why we talk about escape velocity which is independent of mass.
