The sun may appear green due to several factors:
- Atmospheric Scattering: When the sun is low in the sky, such as during sunrise or sunset, its light passes through more atmosphere, scattering shorter wavelengths (green, blue, violet) and making it appear yellow, orange, or red1.
- Emission Spectrum: The sun emits light most strongly in the green part of the spectrum, specifically at a wavelength of 500.7 nanometers2.
- Visual Perception: Our eyes cannot perceive the actual color of the sun, which is said to be green; instead, we see it as yellow or white due to atmospheric effects3.
- Space Observation: If viewed from space, the sun appears white because it emits strongly across all visible colors, including green5.
Thus, while the sun emits green light, atmospheric conditions and human perception affect how we see it.
