Which Planet Has the Strongest Gravity?

Jupiter, the largest planet in the solar system with a mass of about 1.9 x 10 to the 27 kg (318 times Earth mass), exerts the strongest gravitational pull of any planet. Its surface gravity (measured at the cloud tops, since Jupiter has no solid surface) is approximately 24.8 m/s squared, compared to Earth 9.8 m/s squared — about 2.53 times stronger. Despite being 318 times more massive than Earth, Jupiter gravity is only 2.53 times stronger because gravity also depends on the square of the radius, and Jupiter is about 11 times wider than Earth. Saturn, despite being the second-largest planet, has surprisingly weak surface gravity (10.4 m/s squared, only slightly more than Earth) because of its very low density — Saturn is less dense than water. Among all solar system bodies, the Sun dominates with surface gravity of 274 m/s squared (28 times Earth), and neutron stars can reach billions of times Earth gravity.
