Voyager 2 crosses the termination shock at about 84 AU

node

Voyager 2 met the shock roughly ten astronomical units closer to the Sun than Voyager 1 had, and crossed it more than once as the shock itself moved in and out with solar activity. The distance asymmetry between the two crossings was among the first direct evidence that the heliosphere is not spherical. Because Voyager 2's plasma science instrument still worked, this crossing produced the first direct plasma measurements of a termination shock.

A node is not a place. Drawing it on a map would assert something about the world that no stored fact supports.

  47. Voyager 2 crossed the termination shock on 30 August 2007 at about 84 AU, roughly ten AU closer to the Sun than Voyager 1's crossing, indicating an asymmetric heliosphere; the shock was crossed more than once as it moved with solar activity.
