Suspicous0bservers | If you want to know the sun and how it interacts with our planet Earth, the most important thing to learn about is the Solar Wind. While gravity is constantly pulling it just like on Earth, there is an outward force to the sun as well and it affects tiny particles in and around the atmosphere of the sun. This force pushes these tiny particles out in all directions. They travel from the Sun all the way out past the planets, even farther than Pluto. There is nothing in our Solar System that is not touched and affected by the Solar Wind. So we need to know what the Solar Wand is.
