When At 15.6 million degrees Celsius the temperature of the sun's core is high enough for nuclear to occur?

At temperatures of about 15.6 million degrees Celsius, the conditions in the sun's core are ideal for nuclear fusion to occur. In this process, hydrogen nuclei combine to form helium, releasing vast amounts of energy in the form of light and heat. This energy production is crucial for the sun's stability and is what powers the solar system. The immense gravitational pressure in the core facilitates these fusion reactions despite the repulsive forces between positively charged protons.
