Detailed explanation-1: -The Moon’s smaller mass and radius combine to produce a gravitational field at its surface only one-sixth that of our Earth. The Moon’s much weaker gravity corresponds to an escape speed of only 5400 mph, a speed gas molecules can attain.
Detailed explanation-2: -Thus, the gravitational attraction on the Moon is much less than it is here on Earth, and a person weighs less on the Moon. This weaker gravity is why we have the famous images of the Apollo astronauts taking “one giant leap for mankind” on the Moon’s surface.
Detailed explanation-3: -The gravitational force between Earth and the moon is strong. But the force is not strong enough to pull the moon towards us, like an apple falling from the tree due to Gravity.
Detailed explanation-4: -The Sun Has a Lot of Pull! The Sun’s gravity is about 27.9 times that of Earth, and, in a small way, it helps to control the tides on Earth.
