The stream of charged particles given off from the Sun is called the solar wind. The solar wind is composed primarily of protons and electrons, with smaller amounts of heavier ions. It is a continuous flow of charged particles that extends throughout the solar system, driven by the high temperature and intense magnetic activity of the Sun's outer atmosphere, known as the corona. The solar wind interacts with planetary magnetic fields and can have various effects on celestial bodies and their environments, including the creation of auroras and the erosion of planetary atmospheres.
