Sep 13, 2016 · Although the Sun is mostly just a ball of hydrogen and helium, it’s actually broken up into distinct layers. The layers of the Sun are created because the temperatures and pressures increase as...
Sun - Wikipedia
Roughly three-quarters of the Sun's mass consists of hydrogen (~73%); the rest is mostly helium (~25%), with much smaller quantities of heavier elements, including oxygen, carbon, neon, and iron. The Sun is a G-type main-sequence star (G2V), informally called a yellow dwarf, though its light is actually white.

Oct 10, 2012 · This graphic shows a model of the layers of the Sun, with approximate mileage ranges for each layer: for the inner layers, the mileage is from the sun’s core; for the outer layers, the mileage is from the sun’s surface. The inner layers are the Core, Radiative Zone and Convection Zone.
