The sun is a star that is the center of our solar system, providing light and heat to Earth and other planets: Location: The sun is located about 93 million miles (150 million kilometers) from Earth. Size: The sun is much larger than Earth, with a radius that is about 109 times that of Earth. Composition: The sun is made of plasma, a super-hot, electrically charged gas. Temperature: The sun's core is heated to incandescence by nuclear fusion reactions. Energy: The sun is the primary source of energy for life on Earth. It radiates energy from its surface as visible light, infrared radiation, and ultraviolet energies. Gravity: The sun's gravity holds the solar system together, keeping the planets, asteroids, comets, and space debris in orbit. Layers: The sun has multiple layers, including the photosphere, chromosphere, and corona. Rotation: The sun rotates at different speeds at different parts of its surface. At its equator, the sun rotates once every 25 Earth days, while at its poles it rotates once every 36 Earth days. Future: The sun has enough nuclear fuel to remain as it is for another 5 billion years. After that, it will swell into a red giant, shed its outer layer
