Where is the heliopause?
Quick Answer
The heliopause is the outer boundary of the Sun’s influence in interstellar space. It marks where the solar wind is pushed back by the thin gas between stars.
The Full Story
The heliopause lies far beyond the planets, at the edge of the heliosphere created by the solar wind. It is not a physical wall, but a boundary where the outward pressure of the solar wind balances the pressure of the local interstellar medium. Voyager 1 crossed it in 2012, and Voyager 2 crossed it in 2018. Both spacecraft confirmed that the Sun’s bubble extends much farther than the planetary region.
