Sol is the name of the Sun in our solar system. It is a massive ball of hot plasma, primarily composed of hydrogen and helium. Sol generates energy through nuclear fusion, converting hydrogen into helium in its core, which produces light and heat that sustain life on Earth. Sol is the center of our solar system, and all planets, including Earth, orbit around it due to its strong gravitational pull. It is about 4.6 billion years old and is classified as a G-type main-sequence star, or G dwarf. The energy from Sol drives weather patterns and supports photosynthesis in plants.
