Saturn is significantly larger than Earth in multiple dimensions:

  • Diameter: Saturn's diameter is about 120,000 km (75,000 miles), which is roughly 9 to 10 times the diameter of Earth, whose diameter is about 12,742 km (7,918 miles)
  • Volume: Saturn's volume is about 764 times greater than Earth's, meaning about 764 Earths could fit inside Saturn
  • Surface Area: Saturn's surface area is approximately 42.7 billion square kilometers, about 83.6 times that of Earth’s 510 million square kilometers
  • Mass: Saturn is about 95 times more massive than Earth, despite its much larger size, but its density is much lower (about 0.687 g/cm³ compared to Earth's 5.52 g/cm³) because Saturn is mostly composed of hydrogen and helium

In summary, Saturn is about 9 to 10 times wider than Earth, can contain over 760 Earths by volume, and has about 95 times Earth's mass but much lower density due to its gaseous composition
