The surface temperature of the Sun, specifically its photosphere, is approximately 5,500 degrees Celsius (about 9,932 degrees Fahrenheit). This temperature plays a crucial role in radiating energy into space, influencing climate and weather patterns on Earth. The core of the Sun is much hotter, reaching temperatures around 15 million degrees Celsius (27 million degrees Fahrenheit), where nuclear fusion occurs, generating the enormous energy that powers our solar system. The intense temperature gradient from core to surface is essential for the processes that sustain life on Earth through sunlight and heat.
