We often think of Saturn as a massive, majestic planet with its famous rings. And it is—the second-largest planet in the solar system, over 760 times the volume of Earth. But here’s a twist:
If you could somehow stand on Saturn, you’d actually weigh less than you do on Earth.
Wait… what?
Gravity Depends on More Than Size
Weight isn’t just about mass. It’s about gravity, which is determined by both a planet’s mass and its radius. Despite Saturn’s huge size, it’s made mostly of gas—hydrogen and helium—which makes it very low in density.
In fact, Saturn is the least dense planet in the solar system. It’s so light for its size that it could float in a bathtub (if you could find one that big).
The Numbers
Let’s say you weigh 70 kg (154 lbs) on Earth. On Saturn, you’d weigh about:
-
74 kg (163 lbs) on the cloud tops—just a bit more than on Earth.
But here’s the catch: you can’t actually stand on Saturn. It doesn’t have a solid surface—just a dense atmosphere that gets thicker and hotter as you go deeper.
And if you tried to descend through the clouds, you’d face:
-
Crushing atmospheric pressure
-
Intense winds and storms
-
Eventually, temperatures hot enough to vaporize spacecraft
So technically, your “weight” on Saturn depends on how far into the atmosphere you go—but in the upper layers, gravity is similar to Earth’s.
Comparisons with Other Planets
Just for fun, here’s what you’d weigh elsewhere (assuming 70 kg on Earth):
-
Mars: 26.5 kg (58 lbs)
-
Jupiter: 165 kg (364 lbs)
-
The Moon: 11.5 kg (25 lbs)
-
Pluto: 4.5 kg (10 lbs)
So… How Heavy Would You Be on Saturn?
Not much heavier than on Earth—if you could find a place to stand.
Saturn may be huge, but it won’t crush you with gravity.
It’s not weight—it’s density that tells the real story.
