Detailed explanation-1: -The Moon’s surface gravity is weaker because it is far less massive than Earth. A body’s surface gravity is proportional to its mass, but inversely proportional to the square of its radius. The mass of the moon is 1100times and its radius 14times that of earth.

Detailed explanation-2: -Lowest Gravity Planets The planet with the lowest gravity is Saturn’s moon, Enceladus. It’s surface gravity is only about 0.113 m/s^2, which is about 1/8th that of Earth’s gravity. Enceladus is a small moon, with a diameter of only about 500 kilometers (311 miles).

Detailed explanation-3: -The Earth’s Moon has considerably less mass than the Earth itself. Not only is the Moon smaller than the Earth, but it is only about 60 percent as dense as Earth. Thus, the gravitational attraction on the Moon is much less than it is here on Earth, and a person weighs less on the Moon.

Detailed explanation-4: -Saturn is slightly smaller than Jupiter, and also less massive; therefore, its severity will be less. Its gravitational acceleration is 10, 44 m/s².

Detailed explanation-5: -The Moon’s gravitational pull is relatively weak compared to Earth’s. (Apollo astronauts were able to leap across the lunar surface because of this weaker pull.) Yet, the Moon’s gravitational pull is responsible for Earth’s current length of day, stable seasons, and tides.
