I personally see this “Outside the solar system” claim as a rather subjective declaration.
To me, outside the solar system would be outside the most distant objects orbiting our sun. There are known objects considered to be part of our solar system that are further out than Voyager.
Have NASA get back to me in another 25,000 years or so.
