What is the surface gravity of Jupiter?

Answer 1

Jupiter does not have a solid surface upon which to stand - just many turbulent and increasingly dense layers of gas and liquid - though it may have a very dense, solid core.

However, if you were to stand where the gassy layers give way to liquid (its approximate surface), gravity would be about 25m/s2. That's over two and a half times the gravity on the surface of Earth.

If you weighed 100lbs on Earth (where gravity is 9.8 m/s2), you would weigh about 254lbs on Jupiter, or be around 254% as heavy (or 154% heavier).

This is because, though Jupiter is 318 times the mass of the Earth, it is 11 times greater in diameter. Gravity increases with mass, but decreases with the distance from the centre of mass. The gravitational force is g=m/r2 (gravitational constant x mass of Jupiter x mass of the object, all divided by the distance between the centres of mass squared).

If you could compress the mass of Jupiter down to the size of Earth and attempt to land upon its surface, you would be crushed into oblivion - your weight would be more than 300 times as great as on Earth!
The same thing it is on Earth or anywhere else in the universe . . . the characteristic

of space-time that causes forces of attraction between every two masses.
Gravity on Jupiter is much greater than on Earth because Jupiter is a larger planet, and therefore has much more gravitational pull. Therefore, if you weighed 100 pounds on the Earth, on Jupiter, you would weigh 236.4 pounds. But also the gravitational pull does not count on the size of a planet. While Jupiter is much larger than the Earth, it has a little more than two times the Earth's mass. Saturn, if submerged in water, will actually float because it is less dense than water. Here are more statistics on what a 100 pound person would weigh on other bodies in space:

Mercury: 37.8 lbs

Venus: 90.7 lbs

Mars: 37.7 lbs

Our Moon: 16.6 lbs

Saturn: 106.4 lbs

Uranus: 88.9 lbs

Neptune: 112.5 lbs

Pluto: 6.7 lbs

The Sun: 2,707.2 lbs

White Dwarf Star: 130,000,000 lbs

Neutron Star: 14,000,000,000,000 lbs

Answer 2

Jupiter's surface gravity is about 23.6N/kg, compared with Earth's 9.8 N/kg. Supposedly, this is the pull at the base of the cloud cover. But you still couldn't stand there, as the surface of Jupiter is liquid hydrogen at thousands of degrees (due to atmospheric pressure).

Edit: The surface gravity of Jupiter is normally given for a depth where the

atmospheric pressure is the same as Earth ("1bar"). So the pressure would

not be a problem, but you still couldn't stand there!

Also these values for gravity vary a bit. I've seen 26 Newtons per kg., for

example. It depends a bit on the definition.

Answer 3

The gravity on Jupiter is 2.5 times as much on Earth, as measured at the arbitrary "base" of its atmosphere, which is not the bottom of it. The gases continue to become denser for several thousand miles deeper toward the core.

Answer 4

Surface Gravity:

Metric: 20.87 m/s2

English: 68.48 ft/s2

If you weigh 100 pounds on Earth, you would weigh 214 pounds on Jupiter.

Answer 5

The acceleration due to gravity on Jupiter is about 25 m/s^2

Answer 6

20.87 m/s2

Answer 7

24.79 m/s 2

Answer 8

12.23m/s2
