SOLAR SYSTEM

Detailed explanation-1: -It is the outer layer of the sun that is present outside of the core. Because of this, it is the coldest layer of the sun. The corona is the outermost layer of the sun and it is hotter than the photosphere. The chromosphere is the layer between the corona and photosphere.

Detailed explanation-2: -Edlén and Grotrian’s finding that the sun’s corona is so much hotter than the photosphere – despite being further from the sun’s core, its ultimate source of energy – has led to much head-scratching in the scientific community.

Detailed explanation-3: -The photosphere is much brighter than the outer parts of the Sun’s atmosphere (the chromosphere and the corona), so regular photos of the Sun do not show the outer atmosphere.

Detailed explanation-4: -While the photosphere hovers around 5, 800 kelvin, the temperature of the chromosphere varies between 4, 500 K and 20, 000 K. Even though it’s more distant from the center of the Sun, the chromosphere is hotter than the photosphere.

Detailed explanation-5: -The second outer layer of the sun’s atmosphere is called the chromosphere. This is the middle layer of the sun’s atmosphere. The hydrogen atoms in this layer absorb much of the energy that passes through from the surface of the sun. This energy is converted into red light that is emitted into the corona.
