Saturn and the Earth compared

  • Saturn's diameter is about nine times greater than the Earth's

  • It has 95 times the mass

  • If you weigh 180 pounds on Earth, you would weigh only 165 pounds at Saturn's cloud tops (despite Saturn's enormous mass, its density is so low that if you were able to stand atop Saturn's clouds, you would feel a pull of gravity slightly less than what you feel on the Earth's surface)

  • Saturn is ten times further from the Sun than the Earth

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.
