The Sun, composed of 75% hydrogen and 25% helium by mass, plays a critical role in our solar system. Through the process of nuclear fusion, it converts hydrogen into helium in its core, where conditions reach a staggering temperature of 15.6 million Kelvin and pressure of 250 billion atmospheres. The Sun exhibits differential rotation, taking about 25.4 days to rotate at the equator, while the poles take up to 36 days. This unique behavior and the Sun's composition are vital for maintaining life on Earth.
