Newton’s Third Law of Motion states: ‘To every action there is an equal and opposite reaction’. 

It must be remembered that action and reaction always act on different objects. The Third Law of Motion indicates that when one object exerts a force on another object, the second object instantaneously exerts a force back on the first object. These two forces are always equal in magnitude, but opposite in direction. 

These forces act on different objects and so they do not cancel each other. Thus, Newton’s Third Law of Motion describes the relationship between the forces of interaction between two objects.  

Whenever two bodies interact with each other, the force exerted by the first body on the second is called action. The force exerted by the second body on the first body is called reaction. The action and reaction are equal and opposite. 
By this above explanation taking as a universal reference we can state that when body exists the earth atmosphere and enters into the space the body will not fell any constant force which holds that body on a particular location.
So if a little thrust applied in the perfect vacuum it will run till no end but still vacuum provides resistance very minute amount so, the contact resistance (not yet stated by the sciencetist) applied by the vacuum will stop the body after very light years of distance. But buy the known fact this is which vacuum provides a constant acceleration to the body.
