  1. The sun is made of gases, mostly helium and hydrogen, that are held together by its exceedingly strong gravitational pull. While the sun has no solid surface, it does have a defined structure. The sun has three major structural parts: the core, the radiative zone and the convective zone. The core of the sun encompasses 25 percent of its total radius. The radiative zone, which is the section that surrounds the core, makes up 45 percent of the sun's total radius. Lastly, the exterior ring of the sun, known as the convective zone, covers the last 30 percent of the sun's radius. The sun also has its own atmosphere.
