How do solar winds occur?

Because the temperature of the Sun's outer layer, or corona, is so high that the particles move too quickly for the Sun's gravity to contain them, the atoms on its surface are in the state of plasma, and some of their constituents, electrons and protons, flow outward with the solar wind. The Sun's surface is modified and creates new active areas as a result of the different types of solar wind that are produced by the Sun at varying densities and speeds.

The Sun's strong magnetic field and high temperature cause charged particles to be released continuously from the outer layer of its atmosphere, called the corona, and accelerate to speeds of millions of miles per hour. The solar wind flows outward in all directions, affecting the planets and other solar system objects, and carrying magnetic fields with it.
