Sun's heliosphere. Illustration of the Sun's heliosphere, showing the outward-flowing solar wind and the various boundary regions formed as the Sun and its solar wind interact with the surrounding interstellar medium. The boundaries shown here are the termination shock, the heliopause, and the bow wave. The Sun and its planets are also shown. The heliopause is the boundary where the Sun's solar wind is stopped by the interstellar medium. The termination shock is where the solar wind becomes slower than the speed of sound. The bow wave is where the heliosphere forms a wake as it moves through the interstellar medium.
