Gravity on Saturn

Answer 1

The equatorial acceleration due to gravity on Saturn is 1.065g , just a little bit more than Earth's.

Edit: Yes, that's what most sources seem to say, but not all. There are some difficulties such as defining where the "surface" begins. Also some sources

mean "effective " or "apparent" gravity and that takes into account the

"centrifugal" effect of the planet's rotation.

In fact NASA give different values on different web pages.

This is particularly irritating for Saturn because it means things "weigh"

more, or less, than on Earth, depending on the definition.
Its surface gravity is similar to the Earth's. Some sources say it's a bit more, others say it's a bit less.

Answer 2

Present.

Yes, gravity is present, and the strength of Saturn's surface gravity is very similar to Earth's. Unfortunately different sources of reference give various values ranging from 0.92 times Earth's up to about 1.16 times Earth's.

The value I like to use is 1.065 times Earth's. Hope that helps.

Answer 3

The only problem here is that a planet's gravitational field depends on how far

you are from its center. On Earth, that's easy to define, because the Earth has

a solid surface. That's where most of us spend most of our time, and so we

understand the acceleration of Earth's gravity to be the number we measure

when we're on the solid surface.

Saturn is a 'gas giant' and has no solid surface. So where should we stand in

order to compare its 'gravity' to Earth's ?

What the planetary scientists do, in order to talk about the 'size' and 'gravity'

of the gas giant planets, is: They consider dangling a barometer down into

the gas, from the wispiest thinnest gas out in space near the planet, down

and down as it get thicker and heavier. And when the barometer gets down

to the depth where the pressure of the gas is the same as the sea-level pressure

of Earth's atmosphere, they call that the 'surface', for purposes of talking about

the planet's 'size' and gravitational acceleration.

When you do that for Saturn, you find that its diameter is 9.44 times as long as Earth's diameter.

The acceleration of gravity at that depth in Saturn's 'atmosphere' has been

measured as 10.58 meters/second2 . . . about 8% greaterthan on Earth.

Answer 5

Gavity on Saturn is 1.15 times as much as Earth.

Answer 6

Almost identical to Earth's. A 100 pound person on Earth would weigh 106.4 pounds on Saturn.

Answer 7

Gravity on Saturn is approximately 10.44 m/s^2, which is slightly lower than Earth's gravity. This means objects on Saturn would weigh less compared to Earth.

Answer 8

The force of gravity on Saturn is slightly higher than earth's; a 100 pound object on earth would weigh about 107 pounds on Saturn.

Answer 9

About 8% greater than on Earth.

Answer 10

10.44 m/s²
