Border Blast
First, the solar wind slowed down, it becomes more dense, warm and turbulent. The moment of this transition is called the boundary shock wave (termination shock) and is located at a distance of about 85-95 while. f. from the Sun. (According to data obtained from space station Voyager-1 and Voyager 2, which crossed the border in December 2004 and August 2007.)
Heliosphere and heliopause
Even after about a 40. f. facing solar wind with interstellar matter and finally stops. This boundary separates the interstellar medium of a substance the solar system, called the heliopause. In shape it resembles a bubble, elongated in the direction opposite the movement of the Sun. Region of space bounded by heliopause, is called the heliosphere.
According to the apparatus Voyager, heliopause, the south side was closer than the north (73 and 85 astronomical units, respectively). The exact reasons for this are unknown, according to the first person, asymmetric heliopause can be caused by the action of superweak magnetic fields in interstellar space of the Galaxy.
Main shock wave
On the other side heliopause at a distance of approximately 230 as. f. from the Sun, along the head shock wave (bow shock) occurs with braking space velocity incident on the solar system to interstellar matter.
