How many asteroids have hit the moon?

Answer 1

Well we don't know is the answer to that one. We can't answer that for Earth, let alone a planet with an atmosphere that blocks out a view of the surface. What we do know is it is slightly further away from the asteriod belt than we are, so technically there should be fewer rogue asteroids on paths that cross its orbit than ours. I say technically, obviously being closer to the sun it has travels less distance around the sun that we do. So if a rogue asteroid crosses the path of Earth and Venus, it has more chance of hitting venus because it will be in one particuarly place more often. The same goes with Comets too. Sungrazing comets that cross all the planets orbits are more likely to hit venus than Earth. It's still a very very small chance per comet... but it's a slightly higher small chance in that case!

Answer 2

We don't have a good way to know how many asteroids have hit Mars. We don't even know how many have hit earth. We are still finding the evidence of craters. Additionally, some of the craters here have completely weathered beyond discovery. And Mars, would have some craters that have been "erased" as well.

Answer 3

That is impossible to answer. Thousands even millions.

Since it's creation about four and a half billion years ago it would have been pelted with countless asteroids and meteoroids.
