Saturn and the Earth compared
Saturn has the honor of being the second-largest planet in the Solar System, though it has only 30% the mass of its jovian better Jupiter. Like Jupiter, Saturn is blanketed by thick clouds and is believed to have no solid surface except for a relatively small, Earth-size core of rock and metals.
Special thanks to Björn Jónsson for his Saturn clouds map and rings data.
