Sol

BASIC INFO

Sol, a G-type main-sequence star, is the central celestial body of our solar system, comprising primarily hydrogen and helium. It sustains life on Earth through nuclear fusion reactions in its core, emitting energy across the electromagnetic spectrum and generating the solar wind. Its surface features periodic sunspots and follows an 11-year solar cycle of activity. With layers including the photosphere, chromosphere, and corona, Sol influences Earth's climate, weather, and magnetic environment.
