Which planet has the most surface gravity?
Jupiter is the planet with the most surface gravity.
Jupiter has a surface gravity of 24.79 m/s or 2.528 g. This is nearly three times that of Earth. Jupiter's great surface gravity is likely caused by its size, as it is the largest planet in the solar system.
Saturn, Uranus, and Neptune, the other larger planets in the solar system, have great gravities as well, but none are nearly as huge as Jupiter's.
