The Sun is almost 12 times larger than Saturn. The equatorial circumference of Saturn is 227,349 miles, while the Sun has an approximate circumference of 2,713,406 miles. The Sun has an average radius of 432,450 miles, while Saturn's mean radius is 36,184 miles.
According to NASA, if the Sun had the height of a standard front door, Saturn would be about the size of a basketball. Even though it is only 12 times bigger, the Sun contains almost 3,500 times more mass than Saturn. The Sun makes up roughly 99.8 percent of the entire mass of the Solar System, while Saturn is the only planet that is less dense than water.
