Is it possible for the Moon to crash into the Earth?
Long answer: The Moon is in a stable orbit around Earth. There is no chance that it could just change its orbit and crash into Earth without something else really massive coming along and changing the situation. The Moon is actually moving away from Earth at the rate of a few centimetres per year.
What stops the Moon from crashing into Earth?
Without having the force of Gravity from earth-moon would have just floated away from us. The moon’s velocity and distance from Earth allow it to make a perfect balance between fall and escape. That’s why the moon doesn’t fall on Earth.
What would happen if the Moon lost half its mass?
If the moon were half its mass, then the ocean tides would have been correspondingly smaller and imparted less energy to it. So a less massive moon would nonetheless end up closer than the real one to Earth. The energy given to the moon comes from Earth’s rotation—and to compensate, our planet is slowing down.
How much mass do you lose on the Moon?
Your weight on the Moon is 16.5\% what you would experience on Earth. In other words, if you weighed 100 kg on Earth, you would weigh a mere 16.5 kg on the Moon. For you imperial folks, imagine you tipped the scales at 200 pounds. Your weight on the Moon would only be 33 pounds.

How much would an object on the Moon weigh on Earth?
Being that the moon has a gravitational force of 1.622m/s 2, we multiply the object’s mass by this quanitity to calculate an object’s weight on the moon. So an object or person on the moon would weigh 16.5\% its weight on earth.
Is the moon really that far away from the Earth?
Yes, the moon is really that far away from the Earth. You never see it this way in textbooks because it is too hard to see. Here is the Earth-moon with the moon only 1/5 th the distance it is suppose to be (but the correct relative size). Here you can see the red arrow represents the gravitational force on the moon.
Why does the Sun pull on the Earth more than the Moon?
The answer is the gravitational force which a planet is subject to. Earth has much more mass than the moon. Therefore, the sun pulls on it with greater force, because of the greater mass. You probably are familiar that gravity is a downward force.
Why doesn’t the Moon slow down when it orbits the Earth?
If the moon is orbiting the Earth at a constant speed, it neither speeds up nor slows down. Force pushing perpendicular to the velocity of the object. Let me call this a “sideways” force. If it is just a sideways force, the object doesn’t speed up and it doesn’t slow down.
