Explanation:
Titan's diameter is 50 percent larger than that of Earth's moon. Titan is larger than the planet Mercury but is half the mass of the planet. Titan's mass is composed mainly of water in the form of ice and rock material. Titan has no magnetic field
Explanation:
This view shows a close up of toward the south polar region of Saturn's largest moon, Titan, and show a depression within the moon's orange and blue haze layers near the south pole.

Titan is Saturn's largest moon and the second largest in the solar system (after Ganymede of Jupiter). 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 (the main difference is that, because it is closer to the sun, Earth has always been warmer). According to NASA, "In many respects, Saturn's largest moon, Titan, is one of the most Earth-like worlds we have found to date."
"Titan continues to amaze with natural processes similar to those on the Earth, yet involving materials different from our familiar water," Cassini deputy project scientist Scott Edgington, of NASA's Jet Propulsion Laboratory in Pasadena, California, said in a statement.
Sunlight is quite dim on Titan, and climate is driven mostly by changes in the amount of light that accompanies the seasons.
Data also suggests the presence of a liquid ocean beneath the surface, but it is still to be confirmed. [VIDEO: Tour the Strangest Lakes of Saturn's Moon Titan]
As more planets have been found outside of the solar system, Titan has served as a model of cloudy bodies. Examining the atmosphere of the moon has helped scientists to understand the atmospheres of these distant systems.
"It turns out that there's a lot you can learn from looking at a sunset," said Tyler Robinson of NASA's Ames Research Center in a statement.
Cassini spacecraft at Titan
In 2017, the Cassini spacecraft wrapped up its two-decade-long mission to Saturn. Launched on October 15, 1997, the space craft arrived at Saturn on June 30, 2004. Upon its arrival, Cassini dropped the Huygens probe built by the European Space Agency. Huygens was equipped to study Titan by landing on the Saturn moon and achieved astounding results. For example, many mountains above 10,000 feet high have been identified on the moon. [Video: Future Mission to Saturn's Moon Titan]
The Huygens probe landed via parachute on Jan. 14, 2005. Because of Huygens's observations, Titan became a top priority for scientists. The mission has achieved excellent results, such as taking the highest resolution images ever achieved of this moon´s surface.
During its primary and extended missions, Cassini was able to get fundamental data about Titan's structure and the complex organic chemistry of its atmosphere. It is because of Cassini's findings that scientists suspect the presence of an internal ocean composed of water and ammonia. The spacecraft has also spotted seasonal change, such as when an ice cloud formed in Titan's southern hemisphere in 2015 (suggesting that winter was going to be harsh in that zone).
The focus of the mission, as it relates to Titan, was to find signs of seasonal changes and volcanic activity.
Titan played a dominant role in Cassini's planned ending. The massive moon provided the gravitational boost the spacecraft needed to thread between Saturn's rings in its final months, exploring a never-before-seen region. Titan's boost, which came more than four months before Cassini's suicide plunge, was the point of no return, increasing the spacecraft's velocity by approximately 1,925 mph (3,098 km/h) with respect to Saturn.
"With this flyby we're committed to the Grand Finale," Earl Maize, Cassini project manager at JPL, said in a statement after the April 2017 flyby.
