Voyager 1 being nearly a light-day away is one of those

Voyager 1 being nearly a light-day away is one of those distances that sounds poetic until you remember the signal still travels at light speed and takes almost a full day for a round trip. What I find interesting is that even after crossing the heliopause, we’re still arguing about where the Solar System “ends” — the boundary depends on whether you mean planets, solar wind, gravity, or the distant Oort Cloud.
