The atmosphere of Titan is the layer of gases surrounding Titan, the largest moon of Saturn. It is the only thick atmosphere of a natural satellite in the Solar System. Titan's lower atmosphere is primarily composed of nitrogen (94.2%), methane (5.65%), hydrogen (0.099%)[2]. There are trace amounts of other hydrocarbons, such as ethane, diacetylene, methylacetylene, acetylene and propane, and of other gases, such as cyanoacetylene, hydrogen cyanide, carbon dioxide, carbon monoxide, cyanogen, argon and helium.[3] The atmosphere is cold and reducing. The surface pressure is about 50% higher than Earth at 1.5 bars[4] which is near the triple point of methane and allows there to be gaseous methane in the atmosphere and liquid methane on the surface[5]. The orange color as seen from space is produced by other more complex chemicals in small quantities, possibly tholins, tar-like organic precipitates.[6]
