astrosfääre
The astrosfääre is the vast bubble of interstellar plasma and magnetic fields that surrounds our solar system. It is created by the continuous outflow of charged particles from the Sun, known as the solar wind. This solar wind expands outwards, pushing against the interstellar medium, the diffuse gas and dust that fills the space between stars. The boundary where the solar wind pressure is balanced by the interstellar medium pressure is called the heliopause. Inside the heliopause lies the heliosphere, and the outer edge of this region, where the solar wind is significantly slowed and heated by its interaction with the interstellar medium, is known as the termination shock.
The shape and size of the astrosfääre are not perfectly spherical but are influenced by the density
