The Sun produces a solar wind which contains charged particles such as electrons and protons. They escape the Sun’s intense gravity because of their high kinetic energy and the high temperature of the Sun’s corona.The Sun generates huge amounts of energy by combining hydrogen nuclei into helium. This process is called nuclear fusion.
