The Sun is not only the largest object in our solar system, but it is also a fascinating celestial body with many intriguing characteristics. For instance, it is approximately 4.6 billion years old and is expected to continue shining for another 5 billion years before exhausting its nuclear fuel and evolving into a red giant. The Sun's surface temperature is around 5,500 degrees Celsius (9,932 degrees Fahrenheit), while its core reaches temperatures of about 15 million degrees Celsius (27 million degrees Fahrenheit). Additionally, the Sun's gravity is so strong that it keeps the entire solar system in orbit around it. Another interesting fact is that the Sun emits solar wind, a stream of charged particles that can interact with Earth's magnetic field, causing phenomena such as the auroras. Lastly, the Sun is located about 93 million miles (150 million kilometers) from Earth, a distance known as an astronomical unit (AU), which is a standard measurement used in astronomy.
