As of about a month ago, Voyager 1 was about 115.25 AU or about two thousandths of a light-year from Earth. Two days ago, it was announced that it had entered the heliosheath, passing the boundary where the solar wind from the sun slows to a stop. It is now only about four years from being officially in interstellar space. As one article put it, "the wind is now no longer at Voyager's back" - and as hitchhiker said, we're "tapping the eggshell."
