Tholin..........

Tholin [after the ancient Greek word θολός (tholós) meaning "not clear"] is a heteropolymer molecule formed by solar ultraviolet irradiation of simple organic compounds such as methane or ethane. Tholins do not form naturally on modern-day Earth, but are found in great abundance on the surface of icy bodies in the outer solar system. They usually have a reddish-brown appearance.
