Gegenschein is a faint brightness or glow in the night sky that is seen opposite the Sun, usually in the ecliptic plane. It is part of a phenomenon known as zodiacal light. The gegenschein appears as a small, diffuse patch of light, and it is most noticeable in very dark skies far from any artificial light. This glow is caused primarily by sunlight scattering off interplanetary dust particles that are located in the solar system.
