The law of Inertia states that a body will keep moving with a constant speed it no external unbalanced force acts on it. If we throw something into space, from earth, then it will be forced into orbit. Assuming that it overcomes this gravitational force, there are other objects that will exert a force on it.
It will keep going with a constant speed only if it is released in deep space and with no interfering forces.
