Titan is large enough that it can retain some of the gases emanating from its surface and from below its surface. It has a mass of 1.35X10^23 Kg; earth’s moon has a mass of 7.35X10^22 Kg and the gravitational force is proportional to the product of the masses of the two objects attracting each other. It’s atmosphere is composed of 98.4% Nitrogen and 1.6% Methane (Earth’s atmosphere is 78.08% Nitrogen, 20.95% Oxygen, 0.93% Argon and 0.038% Carbon Dioxide with traces of water vapor. Titan spends part of it’s time orbiting within the magnetosphere of Saturn (it does not have a molten iron core and hence no magnetosphere of its own like Earth) and hence it’s atmosphere is protected from the solar wind.
