The weight of an object is the result of the gravitational force acting on it, which varies from planet to planet due to differences in mass and size. The planet where a given object would weigh the most is Jupiter.
Jupiter has the strongest gravitational pull among the planets in our solar system due to its massive size. For example, an object that weighs 100 pounds on Earth would weigh about 236 pounds on Jupiter because Jupiter's gravity is approximately 2.53 times that of Earth's.
