Question
If a comet suddenly hits the Moon and imparts energy which is more than the total energy of the Moon, what will happen?

Solution
A comet with a small velocity and high mass doesn’t trigger the moon much. It just makes a circular-shaped impact. The moon is meant for the protection of life on earth and to attain stability for the earth's rotation. But a comet with a large mass and with large velocity may destroy the moon completely or its impact makes the moon, go out of its orbit.
