Which Planet has highest Gravitational Force in Our Solar System?
The Milky Way Galaxy is our home galaxy in the universe because it consists of our Solar System. The celestial bodies revolves around the Sun, which includes 8 planets, 180 satellites, comets, meteors and asteroids, together constitute the Solar System. Among all the planets in our solar system, Jupiter is the only planet whose gravity is higher than all planets.
Before moving on to the discussion, firstly know that- “What is gravitational force?”. The gravitational force is a force that attracts any two objects with mass. This force that an object exerts depends on three things; its density, mass, and size. Despite being the third lowest densest planet after Uranus (1.27 grams per cubic centimetre) and Saturn (0.69 grams per cubic centimetre), Jupiter has highest mass and size among other planets in our solar system.
The mass of the Jupiter is 1.898 x 10^27 kilograms (4.184x10 ^ 27 pounds) and in astronomy it is called Jupiter mass or Jovian Mass due to its own mass. In this perspective, the Jupiter planet is almost 2.5 times more massive than other planets in our solar system.
Now, if we see the diameter of the Jupiter, which is 86,881.4 miles (139,822 km) that shows the massiveness of the size. If we compare it with other planets, then we find that it is much larger than second place Saturn at 72,367.4 miles (116,464 km) or our own home planet i.e. Earth at 7,917.5 miles (12,742 km). So we can imagine the vastness of the planet Jupiter and can say that with the exception of Saturn and Sun, we can absorb all the planets in our solar system.
Comparative study of gravitational force to other planets of the Solar System
In astronomy, the Earth's gravitational force is taken as a standard value for calculating the gravitational force of other celestial objects. The gravity of the Earth is 9.807 m/s² (9.807 meters per Second Square) (equivalent to 32.18 feet per Second Square). In other words, we can say if anything drops above the ground, then it fall towards the surface at the speed of 9.8 meters per second.
This information will help us to understand the gravitational force of the Jupiter, i.e. 24.79 m/s² (81.33 ft. /s²). But it is important to know that Jupiter is a gas giant and it does not real surface. Therefore, the gravitational forces of the Jupiter or other gas giant planets are calculated at the top of the cloud.
Hence, the gravitational force of the other gas giant of the solar system cannot compete with the gravitational force of the Jupiter. Because the gravitational force of gas giant like Neptune comes in second at 11.15 m/s² (36.58 ft./s²) followed by Saturn at 10.44 m/s² (34.25 ft./s²) and Uranus at 8.69 m/s² (29.4 ft./s²). With the same time, the terrestrial planets like Venus at 8.87 m/s² (29.1 ft./s²), Mars at 3.711 m/s² (12.8 ft./s²) and Mercury at 3.7 m/s² (12.4 ft./s²) has also no match with the Earth at 9.807 m/s². Above all the comparison, the gravitational force of the Jupiter is incomparable because it has highest among all the Planets of the Solar System (Jovian Planets or Terrestrial Planets).
