Detailed explanation-1: -The core is the source of the Sun’s energy, the site of thermonuclear fusion. At a temperature of about 15, 000, 000 K, matter is in the state known as a plasma: atomic nuclei (principally protons) and electrons moving at very high speeds.

Detailed explanation-2: -The core is the hottest part of the Sun, at 15 million degrees Celsius. This is hot enough to sustain thermonuclear fusion, when hydrogen atoms are fused together to form larger helium atoms.

Detailed explanation-3: -The sun’s atmosphere: Photosphere, chromosphere and corona temperatures. Temperatures in the sun’s atmosphere also vary considerably between the layers. In the photosphere, temperatures reach about 10, 000 degrees F (5, 500 degrees C) according to the educational website (opens in new tab) The Sun Today.

Detailed explanation-4: -Find out about the internal structures of our host star and their different temperatures. The hottest part of our Sun is its core, where nuclear fusion reactions create temperatures up to 15 million degrees Celsius (ºC) or 27 million degrees Fahrenheit (ºF), according to NASA.
