As it is known, there are 8 planets in our solar system, each with a different gravitational force from the other; The gravitational force of a planet is related to its mass, the greater the mass, the greater the gravitational pull.

Based on this, you might think that the larger planets in the solar system have more gravity, but it is not that simple, there is another factor that determines the strength of the planet’s gravity is the amount of its density. If the density is low, its gravity may not be as strong as expected.

How do we calculate the gravity of the planets?

To begin with, in order to understand the gravity of other planets, it is always easier to compare it to the force of gravity on the planet Earth in which we live and test its gravity on a daily basis.

To calculate the gravitational force on a planet, we can calculate the rate at which an object falls due to gravitational acceleration. This rate is 9.81 meters per square second on Earth.

This means that the falling object will fall 9.81 meters every second it falls, assuming no resistance from the air.

It is important to note that for gas giant planets, which do not have a solid surface, the gravitational force at the surface is defined as the gravitational force in the upper atmosphere.

Now let’s start by comparing the gravitational force of the planets of our solar system:

The most massive planet

Jupiter is the largest planet in our solar system, and thus also has the strongest gravitational field of all the planets.

The only celestial body in the Solar System whose gravity exceeds Jupiter’s is the Sun.

Jupiter has a mass of about 318 times that of Earth, yet its surface gravity is not 318 times stronger.

The force of gravity on Jupiter’s surface is two and a half times that of Earth, or 24.8 meters per square second.

Jupiter has a relatively low gravity compared to its mass; Because it is not a very dense planet; Jupiter is mainly composed of the two lightest elements; hydrogen and helium.

Since Jupiter is composed almost entirely of light elements, it has a low density and therefore a low surface gravity as well.

An object weighing 45 kilograms on Earth would weigh about 113 kilograms on Jupiter.

Surface gravity of gas giant planets

If you were to somehow stand in the upper layers of Saturn’s atmosphere, you’d experience a gravitational force a little stronger than Earth’s. If you drop an object, it will accelerate downward at a rate of 10.44 meters per square second. Like Jupiter, Saturn’s relatively small gravity is due to its low density.

In fact, Saturn is the least dense planet in the Solar System, and has less surface gravity than Neptune.

Uranus is about 14.5 times larger than the planet Earth, yet its surface gravity is less than Earth’s, this is because – like all other gas giants – it has a relatively low density, and therefore the surface gravity will be weaker than Earth’s. If you drop an object from the tops of Uranus’ clouds, it will accelerate downward at a rate of 8.69 meters per square second.

Neptune is the farthest planet from the sun with a mass about 17 times the mass of Earth. As a gas giant, Neptune has a very low density, and therefore a relatively low surface gravity. Without any air resistance, the object would fall from Neptune’s upper atmosphere at a rate of 11.15 meters per second squared. The gravity of Neptune’s surface is 1.14 times that of Earth, according to World Atlas.

Surface Gravity of Rocky Planets

Mercury, the closest planet to the sun, is also the smallest and least massive planet in the solar system.

Mercury has a mass of only 0.055 times that of Earth, but despite this small number, Mercury has a surprisingly strong surface gravity thanks to its high density.

If you were standing on the surface of Mercury, you would experience a gravitational force of 3.7 meters per square second, or about 0.38 times the surface gravity on Earth, so your weight would be lighter on Mercury compared to your weight on the surface of other planets.

The closest planet to Earth is Venus, and it happens to be about the same size and mass as Earth. Venus is about 95% the size of the Earth and 80% the mass of the Earth.

At the surface, the acceleration due to gravity is 8.87 meters per square second, or about 0.9 times the surface gravity on Earth. Thus, the gravity of the surface of Venus is slightly greater than the gravity of the surface of Uranus.

Mars is similar to Earth in many ways, but much smaller in size and mass.

Mars is only 0.1 times the mass of Earth, and its surface gravity is not much greater than that of Mercury. But Mars is a rather dense planet, so its surface gravity may be greater than you might expect. At the surface, you would experience a gravitational force of 3.71 meters per square second, or about 0.38 times that of Earth’s surface gravity.
