The atmosphere of the sun is composed of several layers, mainly the photosphere, the chromosphere and the corona. It's in these outer layers that the sun's energy, which has bubbled up from the sun's interior layers, is detected as sunlight.
The innermost layer, the troposphere, contains most of the planet's weather and extends out to 10â15km above the surface. The next layer out, the stratosphere, is drier and less dense and extends out to about 50km. The Sun's UV light breaks down oxygen in the stratosphere to form the Earth's protective ozone layer. The mesosphere, thermosphere, and ionosphere make up the remaining outer layers that extend out to about 100km.
