Question

Which planet has the most surface gravity?

Answer 1

Hint:Before we begin, it's important to understand what gravitational force is. The gravitational force is a force that attracts all mass-bearing objects. The force exerted by an object is determined by three factors: density, mass, and size. Jupiter has the biggest mass and size among the planets in our solar system, while being the third densest planet after Uranus ( \[1.27{\text{g}}m\] per cubic centimetre) and Saturn ( \[0.69gm\] per cubic centimetre).

Complete step by step answer:
Jupiter is the solar system's largest and most massive planet. It has a mean radius of \[69,9116{\text{ }}kilometres\] , making it \[10.97\] times the size of Earth, and a mass of \[1.89861027{\text{ }}kg\] , which is the equal of \[317.8\] Earths. With a mean density of \[1.326{\text{ }}gc{m^{ - 3}}\] , Jupiter, as a gas giant, is inherently less dense than Earth and other terrestrial planets.
Now, coming to the question, Jupiter has the highest surface gravity of all the planets.
Jupiter's surface gravity is \[2.528{\text{ }}g\] or \[24.79{\text{ }}m{s^{ - 1}}\] . This is almost three times the size of the Earth. Jupiter's massive surface gravity is most likely due to its size as the solar system's largest planet.
The three larger planets in the solar system, Saturn, Uranus, and Neptune, all have massive gravity, but none compares to Jupiter's.

Note:It's also important to note that, as a gas giant, Jupiter doesn't have a real surface. If you stood on it, you would descend until you reached its (theorised) solid core. Jupiter's surface gravity (measured as the force of gravity at its cloud tops) is therefore \[24.79{\text{ }}m{s^{ - 1}}\] , or \[2.528{\text{ }}g\] .
