The planet with the strongest gravitational pull is Jupiter. Its pull of 24.79 meters per second-squared is 2.53 times the gravity experienced on Earth. Objects that weigh 100 pounds on Earth would weigh 253 pounds on Jupiter. A planet's distance from the sun is not a factor in its gravitational pull; gravity is actually determined by the planet's mass.
