Scientific definitions for heliosphere
[ hē′lē-ə-sfîr′ ]
The large, roughly elliptical region of space around the Sun through which the solar wind extends and through which the Sun exerts a magnetic influence. The heliosphere extends well beyond the orbits of the planets, and its shape and extent fluctuate with changes to the solar wind and other influences.♦ The boundary between the heliosphere and interstellar space is known as the heliopause.
