SOLAR SYSTEM

Detailed explanation-1: -The photosphere is pretty much the “surface” of the Sun, so it is the layer from which the light that is produced inside the Sun is released. When we look at the light from the Sun we see that it produces an absorption spectrum.

Detailed explanation-2: -The top of the photosphere is significantly cooler, with a temperature of only 4400 Kelvin; thus, the cooler, low-density gas at the top of the photosphere produces absorption lines in the solar spectrum.

Detailed explanation-3: -The layer above the photosphere is the chromosphere. The chromosphere emits a reddish glow as super-heated hydrogen burns off. But the red rim can only be seen during a total solar eclipse. At other times, light from the chromosphere is usually too weak to be seen against the brighter photosphere.

Detailed explanation-4: -The Sun is a 4.5 billion-year-old yellow dwarf star – a hot glowing ball of hydrogen and helium – at the center of our solar system. It’s about 93 million miles (150 million kilometers) from Earth and it’s our solar system’s only star. Without the Sun’s energy, life as we know it could not exist on our home planet.
