SOLAR SYSTEM

Detailed explanation-1: -The core of the Sun is considered to extend from the center to about 0.2 to 0.25 of solar radius (140, 000–170, 000 kilometres (87, 000–106, 000 mi)). It is the hottest part of the Sun and of the Solar System.

Detailed explanation-2: -The Core. The Sun’s core is the central region where nuclear reactions consume hydrogen to form helium. These reactions release the energy that ultimately leaves the surface as visible light. These reactions are highly sensitive to temperature and density.

Detailed explanation-3: -The core is the innermost 10% of the Sun’s mass. It is where the energy from nuclear fusion is generated. Because of the enormous amount of gravity compression from all of the layers above it, the core is very hot and dense. Nuclear fusion requires extremely high temperatures and densities.

Detailed explanation-4: -The core of the sun is its hottest part, reaching 27 million degrees Fahrenheit, or 15 million degrees Celsius, according to NASA. Another blistering temperature comes from the sun’s surface which lingers at 10, 340 degrees Fahrenheit.
