Sunlit Saturn Gas Giant Planet by Cassini Golf Balls

The sixth and second-largest planet, Saturn is a gas giant with a swirling atmosphere, iconic rings made of icy particles, and over 146 moons - the most in our solar system. Its largest moon, Titan, even has a thick atmosphere, while Cassini's 13-year mission revealed wonders like the Great White Spot storm and the metallic liquid state of its hydrogen core. Though we've learned a lot, mysteries like the ring formation and the possibility of moon life wait to be unraveled. - This image is was taken NASA for the public.
