What is Saturn's mass in Earth masses?

Saturn’s mass is 95.16 Earth masses.

That makes Saturn the second-most-massive planet in the Solar System, after Jupiter. Its mass is about 5.68 × 10²⁶ kilograms, despite Saturn having a surprisingly low average density—less than that of water. The planet is mostly hydrogen and helium, with a smaller proportion of heavier elements.

Mass is different from size. Saturn is roughly 9.5 times Earth’s diameter, but its mass is about 95 times greater. Its low density results from its enormous volume and gaseous composition. Saturn’s powerful gravity also helps shepherd its extensive ring system and many moons.

A common mix-up is confusing Saturn with Jupiter. Jupiter has about 318 Earth masses, more than three times Saturn’s mass. Saturn’s famous rings contribute only a tiny fraction of the planet’s total mass; the planet itself overwhelmingly dominates the Saturnian system.
