The primary color of the sun appears white when viewed from space, but it seems yellow from Earth’s surface due to atmospheric scattering. This phenomenon causes shorter blue and violet wavelengths to scatter more, leaving predominantly yellow, orange, and red hues during sunrise and sunset. While the sun emits light across the visible spectrum, its various wavelengths combine to produce white light. Despite its appearance, the sun is actually a massive ball of hot gas, primarily composed of hydrogen and helium, undergoing nuclear fusion that generates enormous energy.
