| The fifteenth of Saturn's known satellites, as well as the largest, is Titan It was discovered in 1655 by Huygens. The Titans, in Greek mythology, were a family of giants, children of Gaia and Uranus. They wanted to rule the heavens, but were overthrown by Zeus and his family. Titan is surrounded by a thick, opaque atmosphere, and the surface can't be seen in visible light. There is some slicht variation in color between northern and southern hemispheres. It's bulk is like that of Callisto, Ganymede, probably Pluto, and Triton. The moon is about half ice water, and half of a rocky material. Most likely, it is in several layers, and its interior may be hot, and the moon very dense. It has a significant atmosphere, unlike all others in the solar system. In many ways, it was like earth when the history of its life began. There is no magnetic field, and sometimes orbits outside of Saturn's magnetosphere, and therefore exposed to solar wind. Study reveals that Titan's rotation is like most of Saturns other moons. Diameter: 5150 km Mass: 1.35e23 kg Orbit: 1,221,830 km from Saturn |
