$SOL
The Sun, also known as Sol, is the center of our solar system and a nearly perfect sphere of hot plasma. It provides the light and heat necessary to sustain life on Earth. Composed mainly of hydrogen and helium, the Sun generates energy through nuclear fusion at its core. Its surface temperature reaches about 5,500°C, while its core exceeds 15 million°C. The Sun's gravity holds the planets, asteroids, and comets in orbit. Solar activity, such as sunspots and solar flares, influences space weather. Though it appears eternal, the Sun is about halfway through its 10-billion-year life cycle.
