Titan.
It is the second largest moon of Saturn measuring 1,530 km across and is the 9th largest natural satellite in the solar system. Iapetus – With a diameter of 1,470 km, it is the 3rd largest moon of Saturn. It was discovered by Giovanni Cassini in 1671. It has a distinct feature of having a bright and dark hemisphere. Dione – The 4th largest moon of Saturn named after a vague character in Greek Mythology. It measures 1,122 km in diameter and is the 15th largest moon in the solar System. Despite its size, its mass exceeds all the moons smaller than itself combined. 1 Titan, at 5,150 km diameter, is the second largest moon in the Solar System and Saturn's largest. 2  Out of all the large moons, Titan is the only one with a dense (surface pressure of 1.5 atm), cold atmosphere, primarily made of nitrogen with a small fraction of methane. The largest of the irregular moons is Phoebe, the ninth moon of Saturn, discovered at the end of the 19th century. The rings of Saturn are made up of objects ranging in size from microscopic to moonlets hundreds of meters across, each in its own orbit around Saturn. Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius about nine times that of Earth. Although only one-eighth the average density of Earth, with its larger volume Saturn is just over 95 times more massive. This does not include the hundreds of moonlets comprising the rings. Titan, Saturn's largest moon, and the second-largest in the Solar System, is larger than the planet Mercury, although less massive, and is the only moon in the Solar System to have a substantial atmosphere. Titan. Discovered by Huygens in 1655, Titan is the largest moon orbiting Saturn, and the second largest moon in the Solar System. It is bigger in diameter than both the planets Mercury and Pluto and also larger than Earth's moon. It contains an atmosphere far thicker than even that of the Earth.  Titan, Saturn's largest moon, and the second-largest in the Solar System, is larger than the planet Mercury, although less massive, and is the only moon in the Solar System to have a substantial atmosphere.

It is the second largest planet in the Solar System, yet it is the least dense-it would float in water if there were a bathtub large enough to hold it. Explanation: Rhea is the second largest moon of Saturn, behind Titan, and the largest without an atmosphere. It is composed mostly of water ice, but has a small rocky core. Rhea 's rotation and orbit are locked together (just like Earth's Moon) so that one side always faces Saturn.  Titan is the largest moon of the planet Saturn. Titan is the second largest moon in our Solar System. The diameter of Titan is 5,150 km (3,200 miles), which is about the distance across the United States. Saturn's moon Titan is one of the few moons in the Solar System with much of an atmosphere. It is also one of the largest moons in the Solar System. Some of Saturn's moons are odd. View full size image. 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 believe that 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). Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius about nine times that of Earth. Although only one-eighth the average density of Earth, with its larger volume Saturn is just over 95 times more massive. Saturn, the sixth planet from the Sun, has beautiful rings composed of ice particles.
