The core of the Sun can reach which temperature?

The core of the sun can reach a temperature of about 27 million degrees Fahrenheit (15 million degrees Celsius) due to the process of nuclear fusion. Fusion occurs when hydrogen atoms collide and combine to form helium, releasing a tremendous amount of energy in the form of heat and light. At such high temperatures, the sun's core can sustain the necessary conditions for fusion reactions to continuously occur, providing the energy that drives the sun and creates its immense heat. This tremendous heat generates the intense radiation and light that we see and feel from the sun.
