9. The Orange World of Titan (1984)

Titan, Saturn's largest moon, is one of the most remarkable bodies in the solar system. With its dense orange clouds and its nitrogen atmosphere it may have a deep ocean made up of methane, with cliffs of solid methane and a steady drip of methane rain. Patrick Moore talks about what is known about this extraordinary 'Earth in deep freeze'.
