Where is the Sun's heliopause?
SpaceHeliosphere
Quick Answer
The heliopause is at the edge of the Sun’s influence on interstellar space. Voyager 1 crossed it in 2012 and Voyager 2 crossed it in 2018.
The Full Story
The heliopause marks the outer boundary of the heliosphere, where the solar wind gives way to interstellar space. It is not a sharp wall but a transition region far beyond the planets. Voyager 1 crossed it in 2012, and Voyager 2 crossed it in 2018, providing direct measurements from beyond the solar bubble. The exact distance changes with solar activity, but it is roughly around 120 astronomical units or more from the Sun.
