The Sun is the star at the center of our solar system. It is approximately 93 million miles away from Earth and has a temperature of about 10,000 degrees Fahrenheit. The Sun generates energy through nuclear fusion and its size is about 109 times that of Earth. Its composition is mostly hydrogen and helium. The Sun’s energy affects Earth’s climate and its lifespan is estimated to be about 10 billion years. Looking directly at the Sun is harmful and should be avoided.
