Cassini-Huygens - Earth and Titan ? - Conclusion

Titan, SATURN'S largest satellite, is a distant world: Car away from the Sun and its close, warm TERRESTRIAL PLANETS. A fair distance from Saturn, too. Seen from Titan, at more than a million kilometers away, Saturn looks like a big yellowish ball, permanently girdled by an icy hoop. The Sun's disk is hard to see at a distance of close to one billion five hundred kilometers, more than nine times farther away than the Earth. As a consequence, our star is a hundred times dimmer there, and the temperatures prevailing on Titan drop to 70 K (- 200 : C) in the atmosphere. This atmosphere is thick enough to make Titan an important but mysterious object in our solar system. Even from a near-by distance, as VOYAGER 1 found out in 1980, the dense cloud decks surrounding the small world obscure any glimpse of its surface, as on Venus.
