‘Giant planets' satellites and rings’ looks at these features, which are common to the four giant planets. An explanation is given of ring-satellite systems, their types of orbit, their width, number, thickness, and composition. What was it that Stanton Peale discovered in 1979 that transformed the study of the outer planets' satellites? A description of Io and Europa is included. Why has Europa's surface history sparked controversy? What is ‘ball of string’ terrain? What are the conditions that need to exist for life to take hold? Could there have been life on Europa? Enceladus, Titan, Miranda, Ariel and Triton are discussed.
