Where particles from the Sun begin to slow and clash with matter from the sparse gas found between the stars. At this point the solar wind slows abruptly from a speed in the range 1.1-2.4 million km/h and becomes denser and hotter. Changes in the speed and pressure of the solar wind cause the termination shock to expand, contract and ripple.
- The location of the termination shock is hard to predict as conditions in interstellar space are not well known.
