A review of Titan’s atmospheric phenomena
International audience Saturn's satellite Titan is a particularly interesting body in our solar system. It is the only satellite with a dense atmosphere, which is primarily made of nitrogen and methane. It harbours an intricate photochemistry, that populates the atmosphere with aerosols, but th...

International audience Saturn's satellite Titan is a particularly interesting body in our solar system.
