The solar core refers to the innermost layer of the Sun, where nuclear fusion occurs. It is located at the center of the Sun and extends approximately 20-25% of the Sun's radius. The conditions in the solar core are extreme, with temperatures reaching about 15 million degrees Celsius (27 million degrees Fahrenheit) and pressures around 200 billion times the atmospheric pressure on Earth.
