All 4 gas giants : Jupiter, Saturn, Uranus, Neptune.
Both mercury and mars have a gravity which is around 38% of earths. Mercury's gravity is 37.8% of earths, Mars' gravity is 37.7% of earths.
Of the planets in our solar system, Mars has the lowest surface gravity of around 38% of earths - over one third. This comes closest to the 25%. We then have moons and dwarf planets, but these have much lower surface gravities.
Of the four inner, rocky planets, Earth is the largest and most massive. As a consequence, it has the highest surface gravity of the four inner planets. The gravity for Venus is around 90% of Earths, while for Mars and Mercury the surface gravity is around 38% of Earths.
The Sun's gravity, at its surface, is about 28 times Earth's surface gravity.
Your weight is directly proportional to the mass and gravity of the planet, if the planet has a greater gravity and mass, you will weigh more.
Neptune and Jupiter
on the surfaceNote:Since the earth's composition is not homogeneous, the gravitational acceleration onthe surface is probably less than what it is some small distance below the surface,but it's certainly greater than at the center.
The larger the mass of an object, the greater the force it will exert on other objects. But as the distance from that object becomes greater, the gravitational pull becomes smaller. For example, the sun has a larger mass than the earth, so gravity on the suns surface would be much greater than on earths surface. Also, as you get further and further away from the earth, the less you are influenced by its gravity.
38% on its surface.
The moon's gravity is about 1/6th of the earth's.
The Gravity becomes less
The percentage of Earth's gravity on the surface of the Moon is about 16.5%.
