Heliosphere

A Heliosphere is a bubble-like region of space dominated by a star (...or several stars), which extends far beyond the orbit of the last planet of a system. It extents well past the Kuiper Belt and into the Oort Clouds. Some call this hypothetical boundary the Hill Sphere.

Description / Specifications

Plasma "blown" out from the star, known as the solar wind, creates and maintains this bubble against the outside pressure of the interstellar medium, the hydrogen and helium gas that permeates the Galaxy.

The solar wind is extremely important to solar sailing ships.

History & Background / Dossier

The Heliosphere represents the symbolic domain of an astrographic hex as designated by the IISS.
