Saturn is an enormous gas giant: about 120,500 km wide at the equator, roughly 9 times Earth’s diameter, and big enough to fit about 760+ Earths inside it.

Quick Scoop: How big is Saturn?

If you’re wondering “how bigis saturn” , the short version is: it’s huge compared to Earth, but still smaller than Jupiter.

  • Equatorial diameter: about 120,500–120,536 km (around 74,900 miles).
  • Polar diameter: about 108,700 km (around 67,500 miles) because it’s squashed at the poles.
  • Average radius: about 58,200 km.
  • Volume: you could fit roughly 760–770 Earths inside Saturn.
  • Mass: about 95 times Earth’s mass.
  • Density: only about 70% the density of water, so in theory it would float in a huge ocean.

Picture this: if Earth were the size of a nickel, Saturn would be about the size of a volleyball.

Mini sections

1. Saturn vs Earth (size feel)

  • Saturn is about 9–9.5 times wider than Earth.
  • Surface area is about 84 times Earth’s.
  • Volume is about 766 times Earth’s.

Tiny scale analogy

  • Earth = small coin (dime or nickel).
  • Saturn = roughly a soccer ball or volleyball.

2. Shape and spin

Saturn isn’t a perfect sphere: it’s noticeably flattened (oblate) because it spins very fast.

  • Day length: just over 10.5 hours.
  • This rapid rotation makes the equator bulge and the poles flatter, giving a big difference between equatorial and polar diameters.

3. How it compares in the solar system

  • Second-largest planet after Jupiter.
  • Diameter is about 84% of Jupiter’s.
  • It has much less mass than Jupiter (about one-third), but nearly 60–80% of Jupiter’s volume, which helps explain its low density.

4. One-line TL;DR

Saturn is a colossal, low‑density gas giant about 120,500 km across, around 9 times Earth’s width and big enough to hold more than 760 Earths inside.
