The celestial object at the center of our solar system is the Sun. It is a star classified as a G-type main-sequence star (G dwarf) and is the most crucial source of energy for life on Earth. The Sun provides light and heat, driving climate and weather systems, as well as photosynthesis in plants. Its gravitational force governs the orbits of planets, asteroids, and comets, making it a vital component of the solar system's structure and stability. Understanding the Sun's characteristics is essential for the study of astronomy and astrophysics.
