On the surface, Earth and Titan seem to share little kinship. Titan is 40 percent of Earth’s diameter. It’s colder, with temperatures plunging to –291° Fahrenheit (–180° Celsius). And, of course, it’s a moon, not a planet. However, on a more fundamental level, Earth and Titan show important similarities. Titan mimics many terrestrial processes and landforms common on Earth.
