Saturn is the second-largest planet in our solar system, after Jupiter. In terms of diameter, Saturn measures about 116,460 kilometers (72,366 miles), which is approximately 9 times wider than Earth's diameter. While it is significantly smaller than Jupiter, it is still much larger than Earth and the other terrestrial planets (Mercury, Venus, Mars). Saturn's large size is accompanied by a low density; it is less dense than water, which is a characteristic feature of gas giants. Its size and distinctive rings make it a prominent and easily recognizable planet in the solar system.
