Titan’s atmosphere is dense and hazy, just like Earth’s. The satellite also features intricate, stable bodies of liquid on its surface. But that’s where the similarities with the Earth end. Titan’s liquid isn’t water, but hydrocarbon (mostly methane). It’s atmosphere — 97% nitrogen, the rest methane and hydrogen.
Titan’s remarkable features make it extremely interesting for astronomers and geologists alike. It may not have water or oxygen, but aside from Earth, Titan is still the only body in the solar system to have an atmosphere and hydrologic system, which has a significant impact on its surface and evolution. However, its hazy atmosphere hinders our view of the surface, and it has been difficult to obtain a global vision of Titan’s geology.
