if you throw less than escape velocity, about the energy you threw with less system losses. if you throw greater than escape velocity, about any energy is possible less system losses, if you allow enough time for it to come back after its trip around the solar system. if you throw it into the milky way, same thing, easier potentials. if you throw it at relativistic velocities, expansion of the universe could play a significant role.
