This is a drawing showing the composition of the interior of Titan.

The Composition of Titan

Titan's atmosphere is roughly 90% Nitrogen, and 10% other complex molecules such as methane. The composition of Titan's atmosphere is very similar to the Earth's which is also 80% Nitrogen.

Titan's interior is primarily composed of water ice of different phases with mountains of ice exposed at its suraface. The drawing shows a possible layout of the different phases of ice in Titan's interior. In this respect, Titan is very much like other icy moons.

Deep inside Titan are to be found the more heavier, rocky and metal elements such as silicates and iron. These form the core of Titan.
