The name of the largest moon of Saturn is Titan. Titan is notable for being the only moon in the solar system with a dense atmosphere, primarily composed of nitrogen, and is larger than the planet Mercury. It boasts a rich and complex climate, featuring liquid methane and ethane lakes and rivers on its surface, making it a unique subject of study for scientists. Titan's atmosphere is also of interest because it contains organic compounds, which raises questions about the potential for life. As part of the Cassini–Huygens mission, Titan was extensively explored, providing valuable data about its geology and climate.
