I have a question that I hope somebody can answer.I keep hearing and reading. How the Voyager probes are now entering the boundary where, the Suns influence no longer effect’s the Solar System.In effect Voyagers 1 and 2 are now, on the verge of entering interstellar space. This make’s them now the furthest man-made object’s sent from Earth.Now the question.If Pioneers 10 and 11 were sent, to Jupiter (Pioneer 10) and Saturn Pioneer 11. During the early 1970’s.Are they both considerably more, distant, and closer to the boundary. Then the Voyager’s are? And possibly closer to the very edge of Interstellar space. Is Voyager travelling faster than Pioneer?

The Pioneers stopped transmitting years ago but the Voyagers are still in contact. This page shows up-to-the-second distances: http://voyager.jpl.nasa.gov/where/index.html
