6th Planet tells the story of a near future where scientists discover that the planet Saturn is rapidly changing, and possibly becoming habitable for humans. Is it Gods work? Can science explain it? Or are there aliens involved? These are the questions that separate a world deprived of its resources into groups, who are all convinced they know the answer. In the midst of the chaos, NASA launches a space mission, with our hero Darius on board, a monkey from NASA's "Animals to Mars" program. His mission: to find out what exactly is going on with Saturn, and if these changes are hostile or friendly to us. The 6th Planet comic follows the mission of Darius, and how the situation on Earth takes a turn for the worse.
