An astronomical illustration of the position in the solar system of probes Pioneer and Voyager. These objects are leaving the Solar System because their velocity and direction are taking them away from the Sun, and at their distance from the Sun, its gravitational pull is not sufficient to pull these objects back or into orbit. They are not impervious to the gravitational pull of the Sun and are being slowed down, but they have enough velocity to coast into interstellar space, i.e. retaining sufficient escape velocity to leave the Solar System.
