Not really the Devil's Advocate!
It is the definitions that people do not fully understand (I always look them up to be sure myself).
First off, the heliopause is the flow of particles (solar wind) and the protective magnetic bubble emanating from the sun. It shrinks and grows so
there is no real set distance. Probably why they waited to make the announcement that V2 has indeed left the sun's bubble.
The next, the sun's gravity, is a "best guess" because we have never been out so far! The guess is 1- to 2- light years. At some point the sun's
gravity will be off set by other stars/objects/(tractor beam! lol). A light year, of course, is how far light travels in the vacuum over the period of
a year. The radio signals from Voyagers are still being measured in hours! [added link below]. BTW, the googles says, "1 year = 8760 hours", so there
is still a long way to travel!
Reading/source material, universetoday.com - Characteristics of the Sun
Exit the heliopause? Yes. Technically, that is considered "between star" space.
Exit the sun's overall influence? Nope.
ETA: NASA webpage: Voyagers Telemetry
, says "20 H 5 M one-way light time"! Calculator says we
need 438 total V2 mission times to get out to a light year! *poof*
PS - A friend of the devil is a friend of mine!
