Moon of Saturn, Titan

Hello everyone,

Today I am gonna write about the most beautiful moon in our galaxy: Moon of Saturn, Titan. Well, I don't know what is your opinion about it but I said the most beautiful moon in our galaxy because Titan is the only known place to have liquids in the form of rivers, lakes, and seas on its surface (Except the World).

Moon of Saturn, Titan

Saturn has 82 moons and Titan is one of them. Titan is the largest moon of Saturn. At the same time, it is the second-largest natural satellite in the Solar System. Titan is larger than the planet Mercury (Nasa Solar System Exploration). Among the more than 150 known moons of our solar system, Titan has an important atmosphere. What is more, it has liquid in the form of rivers, lakes and seas on its surface. Titan's atmosphere, like Earth's, is mostly made up of nitrogen, but its surface pressure is 50 percent higher than Earth's. Titan’s atmosphere is much colder, having a temperature at the surface of 94 K (−290 °F, −179 °C), and it contains no free oxygen. Titan has clouds, rain, rivers, lakes and seas of liquid hydrocarbons (e.g. methane and ethane). The largest seas are hundreds of feet deep and hundreds of miles wide. The bottom of Titan's thick water ice crust is more liquid - an ocean mainly made up of water rather than methane.

Life on Titan

Titan's groundwater could be a place to host life as we know it. However, surface lakes and seas of liquid hydrocarbon may have different chemistry, I mean they may harbor life we ​​don't know yet. Titan can also be a lifeless world.

Exploration

Titan was discovered on March 25, 1655, by the Dutch astronomer Christiaan Huygens. Titan was the sixth moon ever discovered, after Earth's Moon and the Galilean moons of Jupiter.
Titan is officially numbered as Saturn VI because after the 1789 discoveries the numbering scheme was frozen to avoid further confusion (Titan bore the numbers VI as well as II and IV). Since then many smaller moons have been discovered closer to Saturn.
