The planet in our solar system with the most gravity is Jupiter. As the largest planet, Jupiter’s gravity is about 24.79 m/s², significantly stronger than Earth's gravity of approximately 9.81 m/s². This immense gravitational force is a result of its massive size and composition, which consists mainly of hydrogen and helium. Jupiter's gravity plays a vital role in the dynamics of the solar system, influencing the orbits of other celestial bodies and even capturing comets and asteroids. Its powerful gravitational field also contributes to its extensive system of moons and its prominent rings.
