In some respects, the surface of Titan is one of the most Earth-like places in the solar system. However, two properties distinguish the surface of Titan from that of Earth: temperature and chemistry. Titan's mean surface temperature is −180°C (∼90 K), and water-ice plays the role that igneous and other types of silicate rocks play in the Earth's crust.
