How big is Saturn compared to Earth?
9.1×wider than Earth
Saturn is 9.1× wider than Earth — 116,460 km across against Earth’s 12,742 km. By volume, about 764 Earths would fit inside Saturn. It has 95.2× Earth’s mass, and its cloud-top gravity is 1.06× Earth’s.

Line up 9 Earths side by side and they’d just span Saturn’s width — but volume grows with the cube of width, so it takes about 764 Earths to actually fill it.
What that actually feels like
Saturn’s rings span about 280,000 km — three quarters of the distance from Earth to the Moon — yet in places they are only around ten metres thick: proportionally thinner than a sheet of paper the size of a city. They are made of countless chunks of nearly pure water ice, from dust grains to house-sized boulders, each on its own orbit.
Ratios on a page are easy to nod along to and impossible to picture. In the interactive view, switch to True scale to see Saturn and Earth at their honest relative sizes — the gap is even more startling than the numbers suggest.
