Saturn is a big planet. The largest planet in the Solar System is Jupiter, but Saturn comes in second. And it’s much larger than Earth.
Let’s start with mass. The mass of Saturn is 5.6846Ã—1026 kg. Just for comparison, this is about 95 times the mass of the Earth. Of course, the mass of Saturn is only 1/3rd the mass of Jupiter.
Next, diameter. The diameter of Saturn is 120,536 km across its equator (and 108,728 from pole to pole). And for comparison, this is about 9.4 times the diameter of the Earth.
Now volume. The total volume of Saturn is 8.2713Ã—1014 cubic km. You could fit 764 Earths nicely inside the volume of Saturn.
And finally, surface area. The surface area of Saturn is 4.27 x 1010 square km. This is almost 84 times the surface area of the Earth.
