Energy from the Sun drives almost everything we see and do on Earth. Our Sun is a star with certain characteristics and behaviour. The influence of the Sun stretches to the 'heliopause', at which point its 'solar wind' is balanced off by incoming radiation pressure from the cosmos. The volume of space contained within this dynamically changing 'heliopause shell' is called the 'heliosphere'.
