The equatorial diameter of Saturn is approximately 120,536 kilometers (74,898 miles). Saturn's shape is oblate, meaning its diameter at the poles is smaller—about 108,728 kilometers (67,560 miles)—due to its rapid rotation causing flattening at the poles and bulging at the equator. Saturn's diameter is about 9.4 times that of Earth, making it the second-largest planet in the Solar System after Jupiter.
