ADVERTISEMENT Spanning hundreds of years in human history, people have always looked up at the stars with a fascination for what is beyond our Earth. Earth’s gravity is 9.807 m/s², compared to the moon’s gravity of 1.62 m/s² or just 17 percent of Earth’s gravity. • The earth’s gravitational field is very precisely mapped, while gravitational field of the moon is poorly mapped. It constantly moves around us. According to NASA, the mass of the Earth is 5.97 x 1024 kg, the mass of the Moon is 7.3 x 1022 kg, and the mean distance between the Earth and the Moon is 3.84 x 108 m. What is the force of gravitational attraction between the Earth and the Moon? What is the difference between gravity on earth and moon? Earth Gravity: Moon Gravity: Earth gravity is the total acceleration that is communicated to the objects because of the combined effect of gravitation and the presence of centrifugal force. Difference between Earth and Moon Gravity Tweet Key Difference : The primary difference between the gravities of the Earth and the Moon is that the moon’s gravity is weaker due to the moon being smaller in size, whereas, the earth is bigger in size, and has more massive objects that exert more gravity. • Gravity or gravitational field intensity on the surface of the earth is equal to 9.8 m/s 2, while the gravitational field intensity of the moon on the lunar surface is only 1.63 m/s 2.

This mix of velocity and distance from the Earth allows the Moon to always be in balance between fall and escape. The reason is that the Moon is never still. Due to the gravity present on the surface of the moon, its total acceleration is 1.62 m/s2. Without the force of gravity from the Earth, it would just float away into space.

One could ask why the Moon doesn’t fall on Earth as an apple from the tree.
