Saturn's Earthlike Moon

摘要

Titan Unveiled is the story of the voyage of the Cassini spacecraft to the domain of the giant ringed planet Saturn, the most distant member of the Sun's family known to ancient astronomers. The book, and indeed the mission itself, has a strong focus on the exploration of Saturn's largest moon, a planet-sized body named Titan. Sir John Herschel suggested the name nearly 200 years after the Dutch astronomer Christiaan Huygens discovered the moon (which he called "Luna Saturni") on March 25,1655.
