The center of the sun is called its core. About one-third of the sun is core. Outside the core, around the middle third of the sun, is an area called the radiator zone . In this area, gasses are as dense as water. From the radiator zone up to about 137 miles below the surface is the convective zone .
Gasses here are about one-tenth the density of water and are extremely violent.
Turbulence and convection help carry energy to the sun s surface. The part of the sun we see is its photosphere, or its surface. This is the inner part of the sun s atmosphere. Gasses in the photosphere heat to more than 10,000 degrees. The sun's corona.
