Must be one way or another. Voyager II is making news because it just
hit the 'termination shock'--where solar wind slows down below the speed
of sound. Apparently this region fluctuates depending on solar activity
and interstellar currents. Exciting stuff. Soon it'll be outside the
heliopause which is where solar wind really fades out. Although you can
make a gravitational claim that the solar system's Oort cloud extends
out to a radius halfway to Alpha Centauri it's really amazing how far
these craft have gone.
