Titan is Saturn’s largest moon and the second largest in the solar system (after Ganymede of Jupiter). It was discovered by cristiaan Huygens in 25th March 1655. It is the only moon in the solar system with clouds and a dense, planet-like atmosphere. 

Scientists think conditions on Titan are similar to Earth’s early years . According to NASA, “In many respects, Saturn’s largest moon, Titan, is one of the most Earth-like worlds we have found to date.”

Atmosphere of Titan

An orange haze surrounding Titan kept its surface a mystery for Earth’s scientists until the arrival of the Cassini mission in 2004. Titan’s atmosphere extends about 370 miles high (about 600 kilometers), which makes it a lot higher than Earth’s atmosphere. Because the atmosphere is so high, Titan was thought to be the largest moon in the solar system for a long time. It wasn’t until 1980 that Voyager was close enough to discover it was actually smaller than Ganymede.

Titan’s atmosphere is active and complex, and it is mainly composed of nitrogen (95 percent) and methane (5 percent). Titan also has a presence of organic molecules that contain carbon and hydrogen, and that often include oxygen and other elements similar to what is found in Earth’s atmosphere and that are essential for life. 

There is an unsolved mystery surrounding Titan’s atmosphere: Because methane is broken down by sunlight, scientists believe there is another source that replenishes what is lost. One potential source of methane is volcanic activity, but this has yet to be confirmed.

Magic Island

There is an abundance of methane lakes, which are mainly concentrated near its southern pole. In 2014, scientists found a transient feature they playfully referred to as “Magic Island.” It’s possible that nitrogen bubbles formed in Titan’s oceans sit on the surface for a period of time, creating a temporary island that eventually dissipates .


Composition & structure

Chemical composition:- It consists of 60% rock and 40% of water.

Atmospheric Composition:- Titan’s atmosphere composed of 94.2% nitrogen, 5.65% methane and 0.099% of hydrogen gas.

Internal structure:- Titan is primarily composed of ice and rocky material, which is likely differentiated into a rocky core surrounded by various layers of ice, including a crust of ice Ih and a subsurface layer of ammonia-rich liquid water.

Orbit and rotation

  • It takes 15 days and 22 hours to complete a full orbit of Saturn.
  • It rotation is synchronous to their orbital. One complete revolution take 15day , 22 hours and 41 minute.

Size & volume

  • The radius of Titan is about to 2574.7km almost 0.066 of earth’s and 3.3 of moon.
  • Volume of Titan is 7.16×1010 km3 .
  • It mass is (1.3452±0.0002)×1023 kg (0.0225 Earths) (1.829 Moons)or 1.34×1023 kg
