Which planet in our solar system has the strongest gravity?

The planet with the strongest gravity in our solar system is Jupiter. Gravity depends on both the mass of a planet and its radius. Although Jupiter is not the densest planet, its enormous size and mass make its surface gravity the highest among all planets.

Jupiter has a mass of about 1.9 × 10²⁷ kilograms, which is more than 300 times the mass of Earth. Its diameter is about 142,984 kilometers, making it the largest planet in the solar system. Despite being mostly composed of hydrogen and helium gases, its sheer size produces an immense gravitational pull.

The surface gravity on Jupiter is approximately 24.79 m/s², which is about 2.5 times stronger than Earth’s gravity (9.8 m/s²). This means that if you weigh 60 kilograms on Earth, you would weigh about 150 kilograms on Jupiter.

Other planets also have strong gravity, but none surpass Jupiter. For example, Neptune has a high density but much smaller mass, so its surface gravity is weaker. Mercury and Venus, being small rocky planets, cannot generate gravity close to that of Jupiter. Even Saturn, the second-largest planet, has weaker surface gravity (10.4 m/s²) because it is less dense.

Jupiter’s powerful gravity plays a crucial role in the solar system. It helps protect the inner planets, including Earth, by attracting or deflecting comets and asteroids that might otherwise collide with us. Astronomers often call Jupiter the “cosmic vacuum cleaner” of the solar system for this reason.

In conclusion, the correct answer is Jupiter (Option A), as it is the planet with the strongest gravitational force in our solar system due to its immense mass and size.
