  Earth has a stronger gravitational pull than Mercury, Venus, Mars and Uranus because it has more mass (weighs more). Saturn, Jupiter and Neptune all have gravity stronger than Earth’s. Jupiter is the planet with the strongest gravitational pull in our solar system. It’s nearly 2.5 times stronger than earth’s gravity.
