How big is Saturn compared to Earth?
Data as of July 2026
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.
