So an object or person on the moon would weigh 16.5% its weight on earth. This means that objects weigh less on the Moon than they do on the Earth. Difference in Diameters of Earth and Moon. The earth gravity is very precisely mapped, while the moon gravity is very poorly mapped. In other words, one weighs more at the poles than one does at the equator because of this central force.

Over time, the energy created by the bulging and subsiding transfers from the planet to the moon, nudging it farther and farther out. A comparison of the diameters of the Earth and the Moon show the former has as diameter of 12,742 km (7,918 mi) and the latter has a diameter of only 3,476 km (2,160 mi). The level of gravity on the moon—about 17 percent that of Earth’s—could wreak havoc on bones, muscles, and other organs. Since the Earth, and particularly the oceans, is not perfectly rigid it is stretched out along the line toward the Moon.

The Moon's mass is about 1/80th (1.2%) of the Earth's mass, so the Moon's gravity is much less than the Earth's gravity; specifically, the Moon's gravity is 1/6th (16.7%) of the Earth's gravity. Other related facts: the Moon is 1/4 the size of the Earth by diameter, and 1/50 the size by volume. The gravity of Earth at the equator is 9.789 m/s2, while the force of gravity at the poles is 9.832 m/s2. Therefore, a person would be much lighter on the moon.

The Moon has less mass than the Earth, so its gravity is less than the Earth's gravity. How about volume? • The earth’s gravitational field is very precisely mapped, while gravitational field of the moon is poorly mapped.

As a moon orbits, its gravity pulls on the planet, causing a temporary bulge in the planet as it passes. Gravity on the Moon is much less. Put another way, Earth weighs 81 times more than the moon. This is caused by the moon’s gravity tugging on the planet, which creates a temporary bulge in the planet. Our Moon drifts 1.5 inches (3.8 centimeters) from Earth … The volume of the Moon is 21.9 billion cubic km. The Moon's gravity is one sixth of the Earth's gravity.

That is about 60 percent of … The temperature reaches about 260 degrees Fahrenheit (127 degrees Celsius) when in full sun, but in darkness, the temperatures plummets to about -280 degrees Fahrenheit (-173 degrees Celsius).
