Voyager 2 crosses the heliopause at 119 AU
node
Six years after its twin and about 2.6 AU closer to the Sun, Voyager 2 crossed the boundary with a working plasma instrument aboard. It recorded a boundary layer roughly 1.5 AU thick in which the plasma slowed, heated and roughly doubled in density, then a transition into interstellar plasma that took less than a day. The interstellar plasma outside was measured hotter than models had predicted.
A node is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
