Mass of Saturn

The mass of Saturn is 5.6846Ã—10

kg. Just for a comparison, this is 95 times the mass of the Earth.

Saturn is much larger than Earth; its equator spans 9.4 times the size of our home planet. And yet, it's much less dense. In fact, Saturn has such a low density that it would actually float on water if you could find a pool large enough.

And so, even though it's much larger and more massive than Earth, if you could actually stand on the "surface of Saturn" - which you can't, there's no surface - you would only feel 91% of gravity that we feel here on Earth.

Here's an article from Universe Today explaining

just how big planets can get

, and an article about how Jupiter and the other gas giants might have

gobbled up their moons

while they were forming.
