Titan, at 5,149 km diameter, is the second largest moon in the Solar System and Saturn's largest. [68] [44] 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. [69]
Titan is the largest moon of Saturn and the second-largest in the Solar System.It is the only moon known to have an atmosphere denser than the Earth's and is the only known object in space—other than Earth—on which there is clear evidence that stable bodies of liquid exist.
Enceladus is the sixth-largest moon of Saturn and the 18th-largest in the Solar System. It is about 500 kilometers (310 miles) in diameter, [5] about a tenth of that of Saturn's largest moon, Titan. It is mostly covered by fresh, clean ice, making it one of the most reflective bodies of the Solar System.
The sizes and masses of many of the moons of Jupiter and Saturn are fairly well known due to numerous observations and interactions of the Galileo and Cassini orbiters; however, many of the moons with a radius less than ~100 km, such as Jupiter's Himalia, have far less certain masses. [5]
Saturn has 146 moons with known orbits; 66 of them have received permanent designations, and 63 have been named. Most of them are quite small. Seven moons are large enough to be in hydrostatic equilibrium, including Titan, the second largest moon in the Solar System.
Astronomers believe the mysterious “magic islands” on Saturn’s moon Titan are honeycomb-like frozen clumps of organic material that fall like snow on the moon.
Arrakis Planitia is a planitia (plain) on Titan, the largest moon of the planet Saturn. It is located in Titan's southern hemisphere, between 74 and 80° south and 113–134° east, [1] within the Mezzoramia region. [2] Arrakis Planitia is named after Arrakis, a fictional desert planet that is featured prominently in Frank Herbert's Dune novels ...
Doom Mons is the name of a mountain range and its eponymous peak on Titan, the largest moon of Saturn. A putative cryovolcano, it is the largest mountain range on Titan by volume. It was discovered by the Cassini–Huygens probe in 2005 and officially named in 2012.
