**Overview** After the **[Ganymede](https://solarsystem.nasa.gov/moons/jupiter-moons/ganymede/in-depth/)**, Jupiter’s Moon is the biggest among all the Moons in our Solar System. In the next position as we move down is the **‘Titan’** which is the **second-largest Moon of the Solar system**. The **mass of this Moon is 80% bigger than the earth’s Moon** and in terms of Diameter, it is 50 % bigger than the earth’s. \
**This was discovered in 1655** by a **Dutch astronomer** named **Christiaan Huygens**. It is one of the seven Mon of the planet Saturn and the second most distant from Saturn. **It is the first known moon of Saturn.** Titan is mainly **made up of ice and Rocky material** and sometimes it can be differentiated as the **rocky core** which is surrounded by the layers of ice and also it has **ammonia-rich water** on the [surface](https://www.mindstick.com/forum/907/how-to-surface-a-value-for-more-than-one-row-in-mysql) of it. The [atmosphere](https://www.mindstick.com/news/2058/robin-wordsworth-re-creates-the-atmosphere-of-ancient-mars) of Titan is mostly similar to earth’ because it **contains mostly Nitrogen** in its atmosphere and also wind and water. \
**Orbit and rotation** Titan takes **15 days and 22 hours** in the context of earth time **to cover the full orbit of Saturn**. It is locked in the [synchronous](https://www.mindstick.com/interview/1029/does-windows-communication-foundation-support-both-synchronous-and-asynchronous-messaging) rotation with Saturn and it shows the same face as to its orbit. The **Titan takes a total of 29 earth years to complete the orbit of the Sun** and it is called the **one ‘Saturnian year**’ and the **axis of rotation of this is tilted a little bit as same as earth.** \
**Size and distance** The **[radius](https://www.mindstick.com/blog/405/curve-corners-with-shadow-in-html-using-css3) of titan** is about **2575 Km** and is nearly **50% bigger than the [Moon of earth](https://www.space.com/55-earths-moon-formation-composition-and-orbit.html)**. The distance of titan from Saturn is **1.2 million Km**. and the Saturn’s Moon distance from the **Sun is about 1.4 billion Km.** the Sun **light takes about 80 minutes to reach the Titan.** \
