Jupiter has about 317 times more mass than Earth. What can you infer from this fact? 

• That Jupiter’s gravitational force is much weaker than on Earth’s gravitational force.
• That Jupiter’s gravitational force is much stronger than Earth’s gravitational force.
• That Jupiter’s and Earth’s gravitational forces are equal.
• Mass has no effect on the gravitational force between two objects
