SOLAR SYSTEM

Detailed explanation-1: -The corona is the outermost part of the Sun’s atmosphere. The corona is usually hidden by the bright light of the Sun’s surface. That makes it difficult to see without using special instruments. However, the corona can be seen during a total solar eclipse.

Detailed explanation-2: -The Corona-It is the extended atmosphere of the sun of very high temperatures leading up to 20000000 K. NASA suggests Corona to be the outermost layer of the Sun and not the photosphere. 4. The Heliosphere-It is the weak outermost atmosphere of the Sun.

Detailed explanation-3: -The corona (Figure below) is the outermost part of the Sun’s atmosphere. It is the Sun’s halo, or “crown.” With a temperature of 1 to 3 million K, the corona is much hotter than the photosphere. The corona extends millions of kilometers into space. Sometime you should try to see a total solar eclipse.

Detailed explanation-4: -the corona-the outermost, hot shell of the atmosphere. the chromosphere-a transparent layer between the corona and the photosphere. the photosphere-the visible “surface” of the Sun.

Detailed explanation-5: -The matter in the external part of the atmosphere of the Sun is composed of plasma which has very low density. The composition of the corona is the same as the interior of the Sun, mainly made up of hydrogen but ionized form.
