What is the role of the sun in the solar system?

The sun is the center of the solar system and plays a critical role in maintaining the stability of the system. It is a massive ball of gas that provides light, heat, and energy to the planets that orbit it.

The sun's gravity is responsible for holding the planets in their respective orbits. It is the largest object in the solar system, accounting for 99.8% of its total mass, and its enormous gravity exerts a significant influence on the other bodies in the system. Without the sun's gravitational pull, the planets would drift off into space.

The sun also produces an enormous amount of energy through the process of nuclear fusion. It converts hydrogen atoms into helium and releases a vast amount of energy in the form of light and heat. This energy is essential for life on Earth, as it provides the energy that drives photosynthesis and powers the planet's climate.
