Detailed explanation-2: -Shortly after arriving in July 2004, the spacecraft uncovered the tiny moons of Methone and Pallene, followed up by discoveries of moons such as Polydeuces, Daphnis and Aegaeon.

Detailed explanation-3: -Cassini revealed Saturn’s moons to be unique worlds with their own stories to tell. Cassini showed us the complexity of Saturn’s rings and the dramatic processes operating within them.

Detailed explanation-4: -Cassini’s decade-long mission made it possible to watch changes in Saturn’s dynamic ring system. The spacecraft discovered propeller-like formations, witnessed the possible birth of a new moon and observed what may be one of the most active, chaotic rings in our solar system (Saturn’s F ring).

Detailed explanation-5: -It turns out these complex hydrocarbons are also contributing to the thick orange-brown smog that cloaks Saturn’s largest moon, Titan, researchers say. With a diameter of 3, 200 miles (5, 150 kilometers), Titan is the second-largest moon in the solar system.
