Titan moon

Christiaan Huygens discovered Titan's moon in 1655. (Tate, 2015). Titan's atmosphere is mostly made up of nitrogen and methane. Nitrogen accounts for 95% of the total, with methane accounting for 5%. (Tate, 2015). Other elements found on the moon, such as oxygen and carbon, are similar to those found on Earth and can easily sustain life. As methane evaporates, clouds form, resulting in methane rain on Titan (Tate, 2015). Titan was formed by co-accretion, a mechanism close to that of planet-forming (Tate, 2015).
Titan is Saturn's primary asteroid, but the solar system's second-largest after Jupiter's Ganymede (O'Neill, 2017). Titan is half the size of earth with a mean radius of about 1,600 miles (O'Neill, 2017). Titan is also bigger than the earth’s moon and it has an atmosphere that is similar to the earth. To begin with, the moon is surrounded by water bodies and it even experiences rainfall through a hydrological cycle just like in planet earth (Tate, 2015). Titan also has a dense atmosphere complete with clouds just like on earth. Its density is about 1.88 g/cm3 (O'Neill, 2017) .The only difference perhaps is the fact that Titan is colder than the earth and most of the water bodies are in the form of ice.

Titan’s distance from the sun is about 1,427,000 000 km which make it cold compared to the earth (O'Neill, 2017). The surface temperature in Titans is about negative 179 degrees Celsius which makes the water very hard, in the form of rocks (O'Neill, 2017). The low temperature also allows methane gas to exist in its liquid form. The surface pressure is also higher than that of the earth at 1.6 bars at sea level compared to the earth which is 1bar (Tate, 2015). Titan orbits Saturn at a distance of 759,000 miles and it takes about 15days, 22 hours to have a complete orbit (O'Neill, 2017). Titan, however, has no magnetic field (O'Neill, 2017).
