what happens if you accidentally fire a gun at earth from the moon

Firing a Gun on the Moon
If you were to fire a gun at Earth from the Moon, there’s no need to worry. Since the Moon has a weak gravitational pull, the bullet would not escape its orbit. Instead, it would travel about 13,000 feet before falling back to the lunar surface. However, the situation changes drastically if a gun is fired toward Earth in open space.
Firing a Gun in Open Space
In the vacuum of space, where there is no air resistance, the bullet would continue moving in a straight line indefinitely, according to the laws of physics. If the bullet were perfectly aimed at Earth, it could potentially cause unpredictable damage depending on its impact point.
Reentry into Earth’s Atmosphere
Fortunately, a standard bullet would not survive reentry into Earth’s atmosphere. The extreme heat and friction generated during atmospheric entry would cause it to burn up before reaching the ground. However, if the bullet were specially designed to withstand these conditions, it could, in the worst case, cause damage comparable to that of a grenade.
Conclusion
In conclusion, under no circumstances should a firearm ever be aimed at Earth from space.
